Linus:
    get_pathspec() does turn '.' into an empty string (which is
    correct - git internally does _not_ ever understand the notion of
    "." as the current working directory), but it doesn't ever do the
    optimization of noticing that a pathspec that consists solely of
    an empty string is "equivalent" to an empty pathspec.

The test is to ensure that this behaviour stays.

When paging through the output of git-whatchanged, the color cues help to
visually navigate within a diff. However, it is difficult to notice when a
new commit starts, because the commit and log are shown in the "normal"
color. This patch colorizes the 'commit' line, customizable through
diff.colors.commit and defaulting to yellow.

As a side effect, some of the diff color engine (slot enum, get_color) has
become accessible outside of diff.c.

It makes no sense to accept an mbox via stdin when we
won't accept it on the commandline.

The patch helps the following scenario:

# git init-db
"add file1 with content"
# git checkout -b apply
"edit file1 && commit"

# git checkout -b conflict master
"edit file1 && commit"

# git checkout -b ok master
"add file2"

# git checkout apply
# git format-patch -k -3 master..conflict | git am -k -3
=> git-am fails with a conflict message
# git reset --hard

# git format-patch -k -3 master..ok | git am -k -3
=> git am fails with the same conflict message as above,
=> since it's trying to apply the old .dotest directory

With the patch it complains about an old .dotest
directory instead.

When naming commits, stop walking the parent chain as soon as we find
a commit that already has a name. The parent chain of that commit will
be walked later on in any case (or may even have been walked already).
This avoids O(n^2) behavior; on a tree where show-branch displays 6800
commits, the total run time drops from 77 seconds to 5 seconds.

Log output from SVN doesn't list all the new files that were
added if a new directory was copied from an existing place in
the repository.  This means we'll have to do some extra work and
traverse new directories ourselves.

This has been updated from the original patch to defer traversed
adds until all removals have been done.  Please disregard the
original.

By default, git-tar-tree(1) sets file and directories modes to 0666
or 0777. While this is both useful and acceptable for projects such
as the Linux Kernel, it might be excessive for other projects. With
this variable, it becomes possible to tell git-tar-tree(1) to apply
a specific umask to the modes above. The special value "user"
indicates that the user's current umask will be used. This should be
enough for most projects, as it will lead to the same permissions as
git-checkout(1) would use. The default value remains 0, which means
world read-write.

This reworks write_out_result() loop so we first remove the paths that

"foo/bar".

When creating a new file where a directory used to be (or the user had
an empty directory) the code did not check the result from lstat() closely
enough, and mistakenly thought the path already existed in the working tree.

This does not fix the problem where you have a patch that creates a file
at "foo" and removes a file at "foo/bar" (which presumably is the last file
in "foo/" directory in the original).  For that, we would need to restructure
write_out_results() loop.

When path foo/bar existed in the working tree, checkout -f to switch to

I've found that git apply is incapable of handling patches
involving object type changes to the same path.

Of course git itself is perfectly capable of making commits that
generate these changes, as it only tracks trees states.  It's
just that the diffs between them are less useful if they can't
be applied.

Some of these are rare, but I've hit one of them (file becoming
a symlink) recently in real-world usage, and was inspired to
find more potential breakages :)

I'm not sure when I'll have time to fix these myself and I'm not
very familiar with the apply code.   So if someone could get
some or all of these cases working, they would be my hero :)

Some of these are what I would refer to as corner-cases from
hell.  Most (if not all) other systems fail some of these.  In
fact, they aren't even capable of representing most of these
changes in their histories; much less being able to handle
patches to that effect.

The core function used in show-branch, join_revs(), was supposed
to be exactly the same algorithm as merge_bases(), except that
it was a version enhanced for use with more than two heads.
However, it needed to mark and keep a list of all the commits it
has seen, because it needed them for its semi-graphical output.
The function to implement this list, mark_seen(), stupidly used
insert_by_date(), when it did not need to keep the list sorted
during its processing.  This made "show-branch --merge-base"
more than 20x slower compared to "merge-base --all" in some
cases (e.g. between b5032a5 and 48ce8b0 in the Linux 2.6 kernel
archive).  The performance of "show-branch --independent"
suffered from the same reason.

This patch sorts the resulting list after the list traversal
just once to fix these problems.
