Commit 334d28ae factored out git.o as an intermediate stage between
git.c and git$X. However:
- It left some no-longer-relevant flags in the rule for git$X.
- It failed to replace git$X with git.o in the list of files that
record GIT_VERSION. This broke incorporation of a changed
GIT_VERSION into git$X because, when GIT_VERSION changes, git.o isn't
remade and git$X is relinked from the git.o that still contains the
old GIT_VERSION.
This patch removes the irrelevant flags and fixes incorporation of a
changed GIT_VERSION into git$X.

Two-file merges were rare enough that they were dropped outside of the
radar. This fix is a trivial change to builtin-rerere.c::find_conflict().
It is still sane to insist that we do not do rerere for symlinks, and
require to have stages #2 and #3, but we can drop the requirement to have
stage #1. rerere does not use information from there anyway.
This fix is from Junio, together with two tests to verify that it works
as expected.

Some source material (e.g. Subversion dump files) perform directory
renames without telling us exactly which files in that subdirectory
were moved. This makes it hard for a frontend to convert such data
formats to a fast-import stream, as all the frontend has on hand
is "Rename a/ to b/" with no details about what files are in a/,
unless the frontend also kept track of all files.
The new 'R' subcommand within a commit allows the frontend to
rename either a file or an entire subdirectory, without needing to
know the object's SHA-1 or the specific files contained within it.
The rename is performed as efficiently as possible internally,
making it cheaper than a 'D'/'M' pair for a file rename.

Our file browser was showing bad output as it did not properly buffer
a partial record when read from `ls-tree -z`. This did not show up on
my Mac OS X system as most trees are small, the pipe buffers generally
big and `ls-tree -z` was generally fast enough that all data was ready
before Tcl started to read. However on my Cygwin system one of my
production repositories had a large enough tree and packfile that it
took a couple of pipe buffers for `ls-tree -z` to complete its dump.

This is based on patches from Linus Torvalds and Junio Hamano, so the
ideas here are theirs.
This makes gitk use "git log -z --pretty=raw" instead of "git rev-list"
to generate the list of commits, and also makes it grok the "<" and ">"
markers that git log (and git rev-list) output with the --left-right
flag to indicate which side of a symmetric diff a commit is reachable
from. Left-side commits are drawn with a triangle pointing leftwards
instead of a circle, and right-side commits are drawn with a triangle
pointing rightwards. The commitlisted list is used to store the
left/right information as well as the information about whether each
commit is on the boundary.

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.

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.

it is a builtin within that executable.

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

away in future versions of git.

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.

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.

Sometimes switching between branches can take more than a second or
two, in which case `git checkout` would normally have shown a small
progress meter to the user on the terminal to let them know that we
are in fact working, and give them a reasonable idea of when we may
finish.
We now do obtain that progress meter from read-tree -v and include
it in our main window's status bar. This allows users to see how
many files we have checked out, how many remain, and what percentage
of the operation is completed. It should help to keep users from
getting bored during a large checkout operation.

If the user double clicks a branch in the checkout dialog then they

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.

Junio noticed that switching on autosetupmerge unilaterally started
cluttering the config for local branches. That is not the original
intention of branch.autosetupmerge, which was meant purely for
convenience when branching off of remote branches, but that semantics
got lost somewhere.
If you still want that "new" behavior, you can switch
branch.autosetupmerge to the value "all". Otherwise, it is interpreted
as a boolean, which triggers setting up defaults _only_ when branching
off of a remote branch, i.e. the originally intended behavior.

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

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.

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
