There is one remaining issue when --no-reuse-delta option is not
used. It can create delta chains that are deeper than specified.
A<--B<--C<--D E F G
Suppose we have a delta chain A to D (A is stored in full either
in a pack or as a loose object. B is depth1 delta relative to A,
C is depth2 delta relative to B...) with loose objects E, F, G.
And we are going to pack all of them.
B, C and D are left as delta against A, B and C respectively.
So A, E, F, and G are examined for deltification, and let's say
we decided to keep E expanded, and store the rest as deltas like
this:
E<--F<--G<--A
Oops. We ended up making D a bit too deep, didn't we? B, C and
D form a chain on top of A!
This is because we did not know what the final depth of A would
be, when we checked objects and decided to keep the existing
delta. Unfortunately, deferring the decision until just before
the deltification is not an option. To be able to make B, C,
and D candidates for deltification with the rest, we need to
know the type and final unexpanded size of them, but the major
part of the optimization comes from the fact that we do not read
the delta data to do so -- getting the final size is quite an
expensive operation.
To prevent this from happening, we should keep A from being
deltified. But how would we tell that, cheaply?
To do this most precisely, after check_object() runs, each
object that is used as the base object of some existing delta
needs to be marked with the maximum depth of the objects we
decided to keep deltified (in this case, D is depth 3 relative
to A, so if no other delta chain that is longer than 3 based on
A exists, mark A with 3). Then when attempting to deltify A, we
would take that number into account to see if the final delta
chain that leads to D becomes too deep.
However, this is a bit cumbersome to compute, so we would cheat
and reduce the maximum depth for A arbitrarily to depth/4 in
this implementation.

The raw output format is not wonderfully pretty, but it's distinguishable
from a "normal patch" in that a normal patch with just one parent has just
one colon at the beginning, while a multi-parent raw diff has <n> colons
for <n> parents.

ls-files: honour per-directory ignore file from higher directories.
When git-ls-files -o --exclude-per-directory=.gitignore is run
from a subdirectory, it did not read from .gitignore from its
parent directory. Reading from them makes output from these two
commands consistent:

It tried to "restore" GIT_AUTHOR_EMAIL environment variable but
the variable started out as unset, so ended up setting it to an
empty string. This is now caught as an error.

http-fetch: Abort requests for objects which arrived in packs
In fetch_object, there's a call to release an object request if the
object mysteriously arrived, say in a pack. Unfortunately, the fetch
attempt for this object might already be in progress, and we'll leak the
descriptor. Instead, try to tidy away the request.

format-patch: Remove last vestiges of --mbox option
Don't mention it in docs or --help output.
Remove mbox, date and author variables from git-format-patch.sh.
Use DESCRIPTION text from man-page to update LONG_USAGE output. It's
a bit silly to have two texts saying the same thing in different words,
and I'm too lazy to update both.

git-commit: finishing touches.
Introduce --only flag to allow the new "partial commit"
semantics when paths are specified. The default is still the
traditional --include semantics. Once peoples' fingers and
scripts that want the traditional behaviour are updated to
explicitly say --include, we could change it to either default
to --only, or refuse to operate without either --only/--include
when paths are specified.
This also fixes a couple of bugs in the previous round. Namely:
- forgot to save/restore index in some cases.
- forgot to use the temporary index to show status when '--only
paths...' semantics was used.
- --author did not take precedence when reusing an existing
commit.

git-commit: revamp the git-commit semantics.
- "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>'

git-rerere: reuse recorded resolve.
In a workflow that employs relatively long lived topic branches,
the developer sometimes needs to resolve the same conflict over
and over again until the topic branches are done (either merged
to the "release" branch, or sent out and accepted upstream).
This commit introduces a new command, "git rerere", to help this
process by recording the conflicted automerge results and
corresponding hand-resolve results on the initial manual merge,
and later by noticing the same conflicted automerge and applying
the previously recorded hand resolution using three-way merge.
