I didn't add the logic for --before/--after flags, but that should be

This adds a git-rm command which provides convenience similar to
git-add, (and a bit more since it takes care of the rm as well if
given -f).
Like git-add, git-rm expands the given path names through
git-ls-files. This means it only acts on files listed in the
index. And it does act recursively on directories by default, (no -r
needed as in the case of rm itself). When it recurses, it does not
remove empty directories that are left behind.

git-push: Update documentation to describe the no-refspec behavior.
format-patch: pretty-print timestamp correctly.
git-add: Add support for --, documentation, and test.
This adds support to git-add to allow the common -- to separate
command-line options and file names. It adds documentation and a new
git-add test case as well.

When git-reset --hard is used and a subdirectory becomes
empty (as it contains no tracked files in the target tree)
the empty subdirectory should be removed. This matches
the behavior of git-checkout-index and git-read-tree -m
which would not have created the subdirectory or would
have deleted it when updating the working directory.
Subdirectories which are not empty will be left behind.
This may happen if the subdirectory still contains object
files from the user's build process (for example).
[jc: simplified the logic a bit, while keeping the test script.]

- "git commit" without _any_ parameter keeps the traditional
behaviour. It commits the current index.
We commit the whole index even when this form is run from a
subdirectory.
- "git commit --include paths..." (or "git commit -i paths...")
is equivalent to:
git update-index --remove paths...
git commit
- "git commit paths..." acquires a new semantics. This is an
incompatible change that needs user training, which I am
still a bit reluctant to swallow, but enough people seem to
have complained that it is confusing to them. It
1. refuses to run if $GIT_DIR/MERGE_HEAD exists, and reminds
trained git users that the traditional semantics now needs
-i flag.
2. refuses to run if named paths... are different in HEAD and
the index (ditto about reminding). Added paths are OK.
3. reads HEAD commit into a temporary index file.
4. updates named paths... from the working tree in this
temporary index.
5. does the same updates of the paths... from the working
tree to the real index.
6. makes a commit using the temporary index that has the
current HEAD as the parent, and updates the HEAD with this
new commit.
- "git commit --all" can run from a subdirectory, but it updates
the index with all the modified files and does a whole tree
commit.
- In all cases, when the command decides not to create a new
commit, the index is left as it was before the command is
run. This means that the two "git diff" in the following
sequence:
$ git diff
$ git commit -a
$ git diff
would show the same diff if you abort the commit process by
making the commit log message empty.
This commit also introduces much requested --author option.
$ git commit --author 'A U Thor <author@example.com>'

This test depended on "sleep 1" to be enough to dirty the index
entry for a symlink. Alex noticed that on his Cygwin installation
"sleep 1" was sometimes not enough, and after further discussion with
Christopher Faylor, it was brought up that on FAT filesystem timestamp
granularity is 2 seconds so sleeping 1 second is not enough.
For now this patch takes an easy workaround of sleeping for 3 seconds.
Very strictly speaking, POSIX requires lstat to fill only S_IFMT part
of st_mode and st_size for symlinks, and depending on timestamp might
be considered a bug, but we depend on that anyway, so it is better to
test that.

This patch converts a stat() to an lstat() call, thereby fixing the case
when the date of a symlink was not the same as the one recorded in the
index. The included test case demonstrates this.
This is for the case that the symlink points to a non-existing file. If
the file exists, worse things than just an error message happen.

This changes the way the case two branches rename the same path
to different paths is handled. Earlier, the code removed the
original path and added both destinations to the index at
stage0. This commit changes it to leave the original path at
stage1, and two destination paths at stage2 and stage3,
respectively.

This fixes the longstanding "Racy GIT" problem, which was pretty
much there from the beginning of time, but was first
demonstrated by Pasky in this message on October 24, 2005:
http://marc.theaimsgroup.com/?l=git&m=113014629716878
If you run the following sequence of commands:
echo frotz >infocom
git update-index --add infocom
echo xyzzy >infocom
so that the second update to file "infocom" does not change
st_mtime, what is recorded as the stat information for the cache
entry "infocom" exactly matches what is on the filesystem
(owner, group, inum, mtime, ctime, mode, length). After this
sequence, we incorrectly think "infocom" file still has string
"frotz" in it, and get really confused. E.g. git-diff-files
would say there is no change, git-update-index --refresh would
not even look at the filesystem to correct the situation.
Some ways of working around this issue were already suggested by
Linus in the same thread on the same day, including waiting
until the next second before returning from update-index if a
cache entry written out has the current timestamp, but that
means we can make at most one commit per second, and given that
the e-mail patch workflow used by Linus needs to process at
least 5 commits per second, it is not an acceptable solution.
Linus notes that git-apply is primarily used to update the index
while processing e-mailed patches, which is true, and
git-apply's up-to-date check is fooled by the same problem but
luckily in the other direction, so it is not really a big issue,
but still it is disturbing.
The function ce_match_stat() is called to bypass the comparison
against filesystem data when the stat data recorded in the cache
entry matches what stat() returns from the filesystem. This
patch tackles the problem by changing it to actually go to the
filesystem data for cache entries that have the same mtime as
the index file itself. This works as long as the index file and
working tree files are on the filesystems that share the same
monotonic clock. Files on network mounted filesystems sometimes
get skewed timestamps compared to "date" output, but as long as
working tree files' timestamps are skewed the same way as the
index file's, this approach still works. The only problematic
files are the ones that have the same timestamp as the index
file's, because two file updates that sandwitch the index file
update must happen within the same second to trigger the
problem.
