1ac17950e9 Mark strings for translation.
The procedure [mc ...] will translate the strings through msgcat.
Strings must be enclosed in quotes, not in braces, because otherwise
xgettext cannot extract them properly, although on the Tcl side both
delimiters would work fine.

[jes: I merged the later patches to that end.]

d4b0ccd931 git-gui: Initialize Tcl's msgcat library for internationalization
Tcl's msgcat library and corresponding mc procedure can locate a
translated string for any user message, provided that it is first
given a directory where the *.msg files are located containing the
translations.

During installation we will place the translations in lib/msgs/,
so we need to inform msgcat of this location once we determine it
during startup.  Our source code tree however will store all of
the translations within the po/ directory, so we need to special
case this variant.

fc703c209d git-gui: Locate the library directory early during startup
To support a localized version of git-gui we need to locate the
library directory early so we can initialize Tcl's msgcat package
to load translated messages from.  This needs to occur before we
declare our git-version proc so that errors related to locating
git or assessing its version can be reported to the end-user in
their preferred language.  However we have to keep the library
loading until after git-version has been declared, otherwise we
will fail to start git-gui if we are using a fake tclIndex that
was generated by our Makefile.

c80d25dbce git-gui: Correct 'git gui blame' in a subdirectory
David Kastrup pointed out that the following sequence was not
working as we had intended:

  $ cd lib
  $ git gui blame console.tcl
  fatal: cannot stat path lib/console.tcl: No such file or directory

The problem here was we disabled the chdir to the root of the
working tree when we are running with a "bare allowed" feature
such as blame or browser, but we still kept the prefix we found via
`git rev-parse --show-prefix`.  This caused us to try and look for
the file "console.tcl" within the subdirectory but also include
the subdirectory's own path from the root of the working tree.
This is unlikely to succeed, unless the user just happened to have
a "lib/lib/console.tcl" file in the repository, in which case we
would produce the wrong result.

In the case of a bare repository we shouldn't get back a value from
`rev-parse --show-prefix`, so really $_prefix should only be set
to the non-empty string if we are in a working tree and we are in a
subdirectory of that working tree.  If this is true we really want
to always be at the top level of the working tree, as all paths are
accessed as though they were relative to the top of the working tree.
Converting $_prefix to a ../ sequence is a fairly simple approach
to moving up the requisite levels.

9c9f5fa97f git-gui: Do not offer to stage three-way diff hunks into the index
git-apply does not accept a patch that was generated as a three-way
combined diff format such as we see during merge conflicts.  If we
get such a diff in our diff viewer and try to send it to git-apply
it just errors out and the user is left confused wondering why they
cannot stage that hunk.

Instead of feeding a known to be unacceptable hunk to git-apply we
now just disable the stage/unstage context menu option if the hunk
came from a three way diff.  The user may still be confused about
why they cannot work with a combined diff, but at least they are
only confused as to why git-gui is not offering them the action.

875b7c9368 git-gui: Fix "unoptimized loading" to not cause git-gui to crash
If the tclsh command was not available to us at the time we were
"built" our lib/tclIndex just lists all of our library files and
we source all of them at once during startup, rather than trying
to lazily load only the procedures we need.  This is a problem as
some of our library code now depends upon the git-version proc,
and that proc is not defined until after the library was fully
loaded.

I'm moving the library loading until after we have determined the
version of git we are talking to, as this ensures that the required
git-reversion procedure is defined before any library code can be
loaded.  Since error_popup is defined in the library we instead use
tk_messageBox directly for errors found during the version detection.

ce015c213f git-gui: Paper bag fix "Stage Hunk For Commit" in diff context menu
In a13ee29b97 I totally broke the
"Stage Hunk For Commit" feature by making this menu item always
appear in a disabled state, so it was never invokable.  A "teaser
feature", just sitting there taunting the poor user who has become
used to having it available.

The issue caused by a13ee was I added a test to look at the data
in $file_states, but I didn't do that test correctly as it was
always looking at a procedure local $file_states array, which is
not defined, so the test was always true and we always disabled
the menu entry.

Instead we only want to disable the menu entry if the current file
we are looking at has no file state information (git-gui is just a
very confused little process) or it is an untracked file (and we
cannot stage individual hunks).

1e0a92fdf7 git-gui: Don't kill modified commit message buffer with merge templates
If the user is in the middle of a merge and has already started to
modify their commit message we were losing the user's changes when
they pressed 'Rescan' after resolving issues or making changes in
the working directory.

The problem here was our background timer that saves the commit
message buffer.  It marks the commit message buffer as not being
modified when it writes it out to disk, so during the rescan we
assumed the buffer should be replaced with what we read from the
MERGE_MSG file.  So we now only read these files from .git if we
have a valid backup file.  Since we clear it on commit this will
only have an impact while the user is actively editing the current
commit.

4578c5cb69 git-gui: Automatically backup the user's commit buffer
A few users have been seeing crashes in Tk when using the undo key
binding to undo the last few keystroke events in the commit buffer.
Unfortunately that means the user loses their commit message and
must start over from scratch when the user restarts the process.

git-gui now saves the user's commit message buffer every couple of
seconds to a temporary file under .git (specifically .git/GITGUI_BCK).
At exit time we rename this file to .git/GITGUI_MSG if there is a
message, the file exists, and it is currently synchronized with the
Tk buffer.  Otherwise we do our usual routine of saving the Tk buffer
to .git/GITGUI_MSG and delete .git/GITGUI_BCK, if it exists.

During startup we favor .git/GITGUI_BCK over .git/GITGUI_MSG.  This
way a crash doesn't take out the user's message buffer but instead
will cause the user to lose only a few keystrokes.  Most people do
not type more than 200 WPM, and with 30 possible saves per minute
we are unlikely to lose more than 7 words.

We now perform the check after we have been running for at least

floating out in no-mans-land like it did before on Mac OS X.

I had to use a wait of a full second here as a wait of 1 millisecond

d164b7548a git-gui: Change our initial GC hint to be an estimate
Instead of running a full git-count-objects to count all of the loose
objects we can get a reasonably close approximation by counting the
number of files in the .git/objects/42 subdirectory. This works out
reasonably well because the SHA-1 hash has a fairly even distribution,
so every .git/objects/?? subdirectory should get a relatively equal
number of files.  If we have at least 8 files in .git/objects/42 than it
is very likely there is about 8 files in every other directory, leaving
us with around 2048 loose objects.

This check is much faster, as we need to only perform a readdir of
a single directory, and we can do it directly from Tcl and avoid the
costly fork+exec.

All of the credit on how clever this is goes to Linus Torvalds; he
suggested using this trick in a post commit hook to repack every so
often.

c136f2b8b9 git-gui: Perform our own magic shbang detection on Windows
If we cannot locate a .exe for a git tool that we want to run than
it may just be a Bourne shell script as these are popular in Git.
In such a case the first line of the file will say "#!/bin/sh" so
a UNIX kernel knows what program to start to parse and run that.
But Windows doesn't support shbang lines, and neither does the Tcl
that comes with Cygwin.

We can pass control off to the git wrapper as that is a real Cygwin
program and can therefore start the Bourne shell script, but that is
at least two fork+exec calls to get the program running.  One to do
the fork+exec of the git wrapper and another to start the Bourne shell
script.  If the program is run multiple times it is rather expensive
as the magic shbang detection won't be cached across executions.

On MinGW/MSYS we don't have the luxury of such magic detection.  The
MSYS team has taught some of this magic to the git wrapper, but again
its slower than it needs to be as the git wrapper must still go and
run the Bourne shell after it is called.

We now attempt to guess the shbang line on Windows by reading the
first line of the file and building our own command line path from
it.  Currently we support Bourne shell (sh), Perl and Python.  That
is the entire set of shbang lines that appear in git.git today.

70a7595cc0 git-gui: Treat git version as git --version
We know that the version subcommand of git is special.  It does not
currently have an executable link installed into $gitexecdir and we
therefore would never match it with one of our file exists tests.
So we forward any invocations to it directly to the git wrapper, as
it is a builtin within that executable.

c67298902c git-gui: Assume unfound commands are known by git wrapper
If we cannot locate a command in $gitexecdir on our own then it may
just be because we are supposed to run it by `git $name` rather than
by `git-$name`.  Many commands are now builtins, more are likely to
go in that direction, and we may see the hardlinks in $gitexecdir go
away in future versions of git.

02efd48f52 git-gui: Correct gitk installation location
The master Makefile in git.git installs gitk into bindir, not
gitexecdir, which means gitk is located as a sibling of the git
wrapper and not as though it were a git helper tool.

We can also avoid some Tcl concat operations by letting eval do
all of the heavy lifting; we have two proper Tcl lists ($cmd and
$revs) that we are joining together and $revs is currently never
an empty list.

0b81261622 git-gui: Always use absolute path to all git executables
Rather than making the C library search for git every time we want
to execute it we now search for the main git wrapper at startup, do
symlink resolution, and then always use the absolute path that we
found to execute the binary later on.  This should save us some
cycles, especially on stat challenged systems like Cygwin/Win32.

While I was working on this change I also converted all of our
existing pipes ([open "| git ..."]) to use two new pipe wrapper
functions.  These functions take additional options like --nice
and --stderr which instructs Tcl to take special action, like
running the underlying git program through `nice` (if available)
or redirect stderr to stdout for capture in Tcl.

51530d1722 git-gui: Change the main window progress bar to use status_bar
Now that we have a fancy status bar mega-widget we can reuse that
within our main window.  This opens the door for implementating
future improvements like a progress bar.

02087abcce git-gui: Unabbreviate commit SHA-1s prior to display
If the end-user feeds us an abbreviated SHA-1 on the command line for
`git gui browser` or `git gui blame` we now unabbreviate the value
through `git rev-parse` so that the title section of the blame or
browser window shows the user the complete SHA-1 as Git determined
it to be.

If the abbreviated value was ambiguous we now complain with the
standard error message(s) as reported by git-rev-parse --verify,
so that the user can understand what might be wrong and correct
their command line.

d41b43eb4c git-gui: Refactor branch switch to support detached head
This is a major rewrite of the way we perform switching between
branches and the subsequent update of the working directory.  Like
core Git we now use a single code path to perform all changes: our
new checkout_op class.  We also use it for branch creation/update
as it integrates the tracking branch fetch process along with a
very basic merge (fast-forward and reset only currently).

Because some users have literally hundreds of local branches we
use the standard revision picker (with its branch filtering tool)
to select the local branch, rather than keeping all of the local
branches in the Branch menu.  The branch menu listing out all of
the available branches is simply not sane for those types of huge
repositories.

Users can now checkout a detached head by ticking off the option
in the checkout dialog.  This option is off by default for the
obvious reason, but it can be easily enabled for any local branch
by simply checking it.  We also detach the head if any non local
branch was selected, or if a revision expression was entered.

699d5601f5 git-gui: Refactor our ui_status_value update technique
I'm really starting to dislike global variables.  The ui_status_value
global varible is just one of those that seems to appear in a lot of
code and in many cases we didn't even declare it "global" within the
proc that updates it so we haven't always been getting all of the
updates we expected to see.

This change introduces two new global procs:

  ui_status $msg;   # Sets the status bar to show $msg.
  ui_ready;         # Changes the status bar to show "Ready."

The second (special) form is used because we often update the area
with this message once we are done processing a block of work and
want the user to know we have completed it.

I'm not fixing the cases that appear in lib/branch.tcl right now
as I'm actually in the middle of a huge refactoring of that code
to support making a detached HEAD checkout.

311e02a4a5 git-gui: Better handling of detached HEAD
If the current branch is not a symbolic-ref that points to a
name in the refs/heads/ namespace we now just assume that the
head is a detached head.  In this case we return the special
branch name of HEAD rather than empty string, as HEAD is a
valid revision specification and the empty string is not.

I have also slightly improved the current-branch function by
using string functions to parse the symbolic-ref data.  This
should be slightly faster than using a regsub.  I think the
code is clearer too.

7cf0442667 git-gui: Option to default new branches to match tracking branches
In some workflows users will want to almost always just create a new
local branch that matches a remote branch.  In this type of workflow
it is handy to have the new branch dialog default to "Match Tracking
Branch" and "Starting Revision"-Tracking Branch", with the focus in
the branch filter field.  This can save users working on this type
of workflow at least two mouse clicks every time they create a new
local branch or switch to one with a fast-forward.
