583e170706 Fix common path "calculation" from logs of multiple branches.
Need to use min instead of max for prev/cur to avoid out-of-bounds
string access. Also treat "i" as index of the last match instead of
a length because in case of a complete match of the two strings
i was off by one.

defe13a24a Fix clone to setup the origin if its name ends with .git
The problem is visible when cloning a local repo. The cloned
repository will have the origin url setup incorrectly: the origin name
will be copied verbatim in origin url of the cloned repository.

5c08931dfc Use git-tag in git-cvsimport
Currently git-cvsimport tries to create tag objects directly via git-mktag
in a very broken way, e.g the stuff it writes into the tagger field of
the tag object doesn't really resemble the GIT_COMMITTER_IDENT. This makes
gitweb and possibly other tools that try to interpret tag objects to be
confused about tag date and authorship.

Fix this by calling git-tag instead. This also has a nice side effect of
not creating the tag object but only the lightweight tag as that's the only
thing CVS has anyways.

892c41b98a introduce GIT_WORK_TREE to specify the work tree
setup_gdg is used as abbreviation for setup_git_directory_gently.

The work tree can be specified using the environment variable
GIT_WORK_TREE and the config option core.worktree (the environment
variable has precendence over the config option).  Additionally
there is a command line option --work-tree which sets the
environment variable.

setup_gdg does the following now:

GIT_DIR unspecified
repository in .git directory
    parent directory of the .git directory is used as work tree,
    GIT_WORK_TREE is ignored

GIT_DIR unspecified
repository in cwd
    GIT_DIR is set to cwd
    see the cases with GIT_DIR specified what happens next and
    also see the note below

GIT_DIR specified
GIT_WORK_TREE/core.worktree unspecified
    cwd is used as work tree

GIT_DIR specified
GIT_WORK_TREE/core.worktree specified
    the specified work tree is used

Note on the case where GIT_DIR is unspecified and repository is in cwd:
    GIT_WORK_TREE is used but is_inside_git_dir is always true.
    I did it this way because setup_gdg might be called multiple
    times (e.g. when doing alias expansion) and in successive calls
    setup_gdg should do the same thing every time.

Meaning of is_bare/is_inside_work_tree/is_inside_git_dir:

(1) is_bare_repository
    A repository is bare if core.bare is true or core.bare is
    unspecified and the name suggests it is bare (directory not
    named .git).  The bare option disables a few protective
    checks which are useful with a working tree.  Currently
    this changes if a repository is bare:
        updates of HEAD are allowed
        git gc packs the refs
        the reflog is disabled by default

(2) is_inside_work_tree
    True if the cwd is inside the associated working tree (if there
    is one), false otherwise.

(3) is_inside_git_dir
    True if the cwd is inside the git directory, false otherwise.
    Before this patch is_inside_git_dir was always true for bare
    repositories.

When setup_gdg finds a repository git_config(git_default_config) is
always called.  This ensure that is_bare_repository makes use of
core.bare and does not guess even though core.bare is specified.

inside_work_tree and inside_git_dir are set if setup_gdg finds a
repository.  The is_inside_work_tree and is_inside_git_dir functions
will die if they are called before a successful call to setup_gdg.

3520e1e868 filter-branch: also don't fail in map() if a commit cannot be mapped
The map() function can be used by filters to map a commit id to its
rewritten id. Such a mapping may not exist, in which case the identity
mapping is used (the commit is returned unchanged).

In the rewrite loop, this mapping is also needed, but was done
explicitly in the same way. Use the map() function instead.

2766ce2815 filter-branch: Use rev-list arguments to specify revision ranges.
A subset of commits in a branch used to be specified by options (-k, -r)
as well as the branch tip itself (-s). It is more natural (for git users)
to specify revision ranges like 'master..next' instead. This makes it so.
If no range is specified it defaults to 'HEAD'.

As a consequence, the new name of the filtered branch must be the first
non-option argument. All remaining arguments are passed to 'git rev-list'
unmodified.

The tip of the branch that gets filtered is implied: It is the first
commit that git rev-list would print for the specified range.

9840906026 filter-branch: fix behaviour of '-k'
The option '-k' says that the given commit and _all_ of its ancestors
are kept as-is.

However, if a to-be-rewritten commit branched from an ancestor of an
ancestor of a commit given with '-k', filter-branch would fail.

Example:

	A - B
	  \
	    C

If filter-branch was called with '-k B -s C', it would actually keep
B (and A as its parent), but would rewrite C, and its parent.

8b7f5fc1ca cvsimport: add support for new style remote layout
cvsimport creates any branches found in the remote CVS repository
in the refs/heads namespace.  This makes sense for a repository
conversion.  When using git as a sane interface to a remote CVS
repository, that repository may well remain as the 'master'
respository.  In this model it makes sense to import the CVS
repository into the refs/remotes namespace.

Add a new option '-r <remote>' to set the remote name for
this import.  When this option is specified branches are named
refs/remotes/<remote>/branch, with HEAD named as master matching
git-clone separate remotes layout.  Without branches are placed
ion refs/heads, with HEAD named origin as before.

0f32da53df git-gui: Favor the original annotations over the recent ones
Usually when you are looking at blame annotations for a region of
a file you are more interested in why something was originally
done then why it is here now.  This is because most of the time
when we get original annotation data we are looking at a simple
refactoring performed to better organize code, not to change its
semantic meaning or function.  Reorganizations are sometimes of
interest, but not usually.

We now show the original commit data first in the tooltip.  This
actually looks quite nice as the original commit will usually have an
author date prior to the current (aka move/copy) annotation's commit,
so the two commits will now tend to appear in chronological order.

I also found myself to always be clicking on the line of interest
in the file column but I always wanted the original tracking data
and not the move/copy data.  So I changed our default commit from
$asim_data (the simple move/copy annotation) to the more complex
$amov_data (the -M -C -C original annotation).

the status bar to show "copy/move tracking annotations" for the
current file (no -M -C -C) as that set of annotations tells us who
put the hunk here (who moved/copied it).  I'm now calling the -M
-C -C pass "original location annotations" as that's what we're
really digging for.

I also tried to clarify some of the text in the hover tooltip.

5d198d6766 git-gui: Use three colors for the blame viewer background
To prevent neighboring lines that are different commits from using
the same background color we now use 3 colors and assign them
by selecting the color that is not used before or after the line
in question.  We still color "on the fly" as we receive hunks from
git-blame, but we delay our color decisions until we are getting
the original location data (the slower -M -C -C pass) as that is
usually more fine-grained than the current location data.

Credit goes to Martin Waitz for the tri-coloring concept.

0dfed77b3c git-gui: Jump to original line in blame viewer
When the user clicks on a commit link within one of the columns
in the blame viewer we now jump them not just to that commit/file
pair but also to the line of the original file.  This saves the
user a lot of time, as they don't need to search through the new
file data for the chunk they were previously looking at.

We also restore the prior view when the user clicks the back button
to return to a pior commit/file pair that they were looking at.

Turned out this was quite tricky to get working in Tk.  Every time
I tried to jump the text widgets to the correct locations by way
of the "yview moveto" or "see" subcommands Tk performed the change
until the current event finished dispatching, and then reset the
views back to 0, making the change never take place.  Forcing Tk
to run the pending events before we jump the UI resolves the issue.

172c92b475 git-gui: Run blame twice on the same file and display both outputs
We now perform two passes over any input file given to the blame
viewer.  Our first pass is a quick "git-blame" with no options,
getting the details of how each line arrived into this file.  We
are specifically ignoring/omitting the rename detection logic as
this first pass is to determine why things got into the state they
are in.

Once the first pass is complete and is displayed in the UI we run
a second pass, using the much more CPU intensive "-M -C -C" options
to perform extensive rename/movement detection.  The output of this
second pass is shown in a different column, allowing the user to see
for any given line how it got to be, and if it came from somewhere
else, where that is.

This is actually very instructive when run on our own lib/branch.tcl
script.  That file grew recently out of a very large block of code
in git-gui.sh.  The first pass shows when I created that file, while
the second pass shows the original commit information.

up our display somehow.  Since we never use italics for anything
else, I'm going with the idea that italic slant can be used to show
data is missing/elided out at the time being.

fc816d7b85 git-gui: Rename fields in blame viewer to better descriptions
Calling the commit message pane $w_cmit is a tad confusing when
we also have the $w_cgrp column that shows the abbreviated SHA-1s.

So w_cmit -> w_cviewer, as it is the "commit viewer"; and
w_cgrp -> w_amov as it is the "annotated commit + move tracking"
column.  Also changed line_data -> amov_data, as that list is
exactly the results shown in w_amov.

Why call the column "move tracking"?  Because this column holds
data from "git blame -M -C".  I'm considering adding an additional
column that holds the data from "git blame" without -M/-C, showing
who did the copy/move, and when they did it.

c5db65aef3 git-gui: Label the uncommitted blame history entry
If the user runs the blame viewer on a working directory file
instead of a specific commit-ish then we have no value for the
commit SHA1 or the summary line; this causes the history menu
to get an empty entry at the very bottom.  We now look for this
odd case and call the meny entry "Working Directory".
