Avoid using "git-var -l" until it gets fixed.
This is to be nicer to people with unusable GECOS field.
"git-var -l" is currently broken in that when used by a user who
does not have a usable GECOS field and has not corrected it by
exporting GIT_COMMITTER_NAME environment variable it dies when
it tries to output GIT_COMMITTER_IDENT (same thing for AUTHOR).
"git-pull" used "git-var -l" only because it needed to get a
configuration variable before "git-repo-config --get" was
introduced. Use the latter tool designed exactly for this
purpose.
"git-sh-setup" used "git-var GIT_AUTHOR_IDENT" without actually
wanting to use its value. The only purpose was to cause the
command to check and barf if the repository format version
recorded in the $GIT_DIR/config file is too new for us to deal
with correctly. Instead, use "repo-config --get" on a random
property and see if it die()s, and check if the exit status is
128 (comes from die -- missing variable is reported with exit
status 1, so we can tell that case apart).

Add support for explicit type specifiers when calling git-repo-config
Currently, git-repo-config will just return the raw value of option
as specified in the config file; this makes things difficult for scripts
calling it, especially if the value is supposed to be boolean.
This patch makes it possible to ask git-repo-config to check if the option
is of the given type (int or bool) and write out the value in its
canonical form. If you do not pass --int or --bool, the behaviour stays
unchanged and the raw value is emitted.
This also incidentally fixes the segfault when option with no value is
encountered.

that the patch does not change anything but the type stuff in
the diff output. Also changed to avoid "foo ? : bar" construct. ]

Make "git clone" less of a deathly quiet experience
It used to be that "git-unpack-objects" would give nice percentages, but
now that we don't unpack the initial clone pack any more, it doesn't. And
I'd love to do that nice percentage view in the pack objects downloader
too, but the thing doesn't even read the pack header, much less know how
much it's going to get, so I was lazy and didn't.
Instead, it at least prints out how much data it's gotten, and what the
packing speed is. Which makes the user realize that it's actually doing
something useful instead of sitting there silently (and if the recipient
knows how large the final result is, he can at least make a guess about
when it migt be done).
So with this patch, I get something like this on my DSL line:

48.398MB (154 kB/s)
where even the speed approximation seems to be roughtly correct (even
though my algorithm is a truly stupid one, and only really gives "speed in
the last half second or so").
Anyway, _something_ like this is definitely needed. It could certainly be
better (if it showed the same kind of thing that git-unpack-objects did,
that would be much nicer, but would require parsing the object stream as
it comes in). But this is big step forward, I think.

committed if these flags were given to git-commit command.
git-commit also acquires -v flag (it used to mean "verify" but
that is the default anyway and there is --no-verify to turn it
off, so not much is lost), which uses the updated git-status -v
to seed the commit log buffer. This is handy for writing a log

Unlike previous git-commit change, this uses a temporary index
to prepare the index file that would become the real index file
after a successful commit, and moves it to the real index file
once the commit is actually made. This makes it safer than the

remove delta-against-self bit

negative net saving on average.
Said bit would in fact be more useful to allow for encoding the copying
of chunks larger than 64KB providing more savings with large files.
This will correspond to packs version 3.
While the current code still produces packs version 2, it is made future
proof so pack versions 2 and 3 are accepted. Any pack version 2 are

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.

rev-list: omit duplicated parents.
Showing the same parent more than once for a commit does not
make much sense downstream, so stop it.
This can happen with an incorrectly made merge commit that
merges the same parent twice, but can happen in an otherwise
sane development history while squishing the history by taking
into account only commits that touch specified paths.
For example,
$ git rev-list --max-count=1 --parents
addafaf -- rev-list.c
would have to show this commit ancestry graph:
.---o---.
/ \
.---*---o---.
/
93b74bc \
---*---o---o-----o---o-----o
addafaf
d8f6b34 \ /
.---o---o---.
\ /
.---*---.

where 5 independent development tracks, only two of which have
changes in the specified paths since they forked. The last
change for the other three development tracks was done by the
same commit before they forked, and we were showing that three
times.
