I tried the code with pack-objects.c::try_delta(), and was
somewhat dissapointed. The current type-path based heuristics
already limits the delta attempts to similar objects anyway, so
it is not a good place to apply it.
The Net never forgets, so we can resurrect it if we wanted to

Retire git-unresolve and make it into "git-update-index --unresolve".
It processes all paths that follow.
During a merge, you would mark a path that is dealt with with:
$ git update-index hello
and you would "undo" it with:
$ git update-index --unresolve hello

git log: don't do merge diffs by default
Allow "git repack" users to specify repacking window/depth
This is an attempt to address the issue raised on #git channel
recently by Carl Worth.
After a conflicted automerge, "git diff" shows a combined diff
to give you how the tentative automerge result differs from
what came from each branch. During a complex merge, it is
tempting to be able to resolve a few paths at a time, mark
them "I've dealt with them" with git-update-index to unclutter
the next "git diff" output, and keep going. However, when the
final result does not compile or otherwise found to be a
mismerge, the workflow to fix the mismerged paths suddenly
changes to "git diff HEAD -- path" (to get a diff from our
HEAD before merging) and "git diff MERGE_HEAD -- path" (to get
a diff from theirs), and it cannot show the combined anymore.
With git-unresolve <paths>..., the versions from our branch and
their branch for specified blobs are placed in stage #2 and
stage #3, without touching the working tree files. This gives
you the combined diff back for easier review, along with
"diff --ours" and "diff --theirs".
One thing it does not do is to place the base in stage #1; this
means "diff --base" would behave differently between the run
immediately after a conflicted three-way merge, and the run
after an update-index by mistake followed by a git-unresolve.
We could theoretically run merge-base between HEAD and
MERGE_HEAD to find which tree to place in stage #1, but
reviewing "diff --base" is not that useful so....

I personally prefer "ignore_merges" to be on by default, because quite
often the merge diff is distracting and not interesting. That's true both
with "-p" and with "--stat" output.
If you want output from merges, you can trivially use the "-m", "-c" or
"--cc" flags to tell that you're interested in merges, which also tells
the diff generator what kind of diff to do (for --stat, any of the three
will do, of course, but they differ for plain patches or for
--patch-with-stat).
This trivial patch just removes the two lines that tells "git log" not to
ignore merges. It will still show the commit log message, of course, due
to the "always_show_header" part.

This is a fairly straightforward patch to allow "get_sha1()" to also have
shorthands for tree and blob objects.
The syntax is very simple and intuitive: you can specify a tree or a blob
by simply specifying <revision>:<path>, and get_sha1() will do the SHA1
lookup from the tree for you.
You can currently do it with "git ls-tree <rev> <path>" and parsing the
output, but that's actually pretty awkward.
With this, you can do something like
git cat-file blob v1.2.4:Makefile
to get the contents of "Makefile" at revision v1.2.4.
Now, this isn't necessarily something you really need all that often, but
the concept itself is actually pretty powerful. We could, for example,
allow things like
git diff v0.99.6:git-commit-script..v1.3.0:git-commit.sh
to see the difference between two arbitrary files in two arbitrary
revisions. To do that, the only thing we'd have to do is to make
git-diff-tree accept two blobs to diff, in addition to the two trees it
now expects.

When I unified the revision argument parsing, I introduced a simple bug
wrt tags that had been marked uninteresting. When it was preparing for the
revision walk, it would mark all the parent commits of an uninteresting
tag correctly uninteresting, but it would forget about the commit itself.
This means that when I just did my 2.6.17-rc2 release, and my scripts
generated the log for "v2.6.17-rc1..v2.6.17-rc2", everything was fine,
except the commit pointed to by 2.6.17-rc1 (which shouldn't have been
there) was included. Even though it should obviously have been marked as
being uninteresting.
Not a huge deal, and the fix is trivial.

Asking for stat (either with --stat or --patch-with-stat) gives
you diffstat for the first parent, even under combine-diff.
While the combined patch is useful to highlight the complexity
and interaction of the parts touched by all branches when
reviewing a merge commit, diffstat is a tool to assess the
extent of damage the merge brings in, and showing stat with the
first parent is more sensible than clever per-parent diffstat.

This option is very special, since pretty_print_commit() will _remove_
the newline at the end of it, so we want to have an extra separator
between the things.
I added a honking big comment this time, so that (a) I don't forget this
_again_ (I broke "oneline" several times during this printout cleanup),
and so that people can understand _why_ the code does what it does.
Now, arguably the alternate fix is to always have the '\n' at the end in
pretty-print-commit, but git-rev-list depends on the current behaviour
(but we could have git-rev-list remove it, whatever).
With the big comment, the code hopefully doesn't get broken again. And now
things like
git log --pretty=oneline --cc --patch-with-stat
works (even if that is admittedly a totally insane combination: if you
want the patch, having the "oneline" log format is just crazy, but hey,
it _works_. Even insane people are people).

Here's a further patch on top of the previous one with cosmetic
improvements (no "real" code changes, just trivial updates):
- it gets the "---" before a diffstat right, including for the combined
merge case. Righ now the logic is that we always use "---" when we have
a diffstat, and an empty line otherwise. That's how I visually prefer
it, but hey, it can be tweaked later.
- I made "diff --cc/combined" add the "---/+++" header lines too. The
thing won't be mistaken for a valid diff, since the "@@" lines have too
many "@" characters (three or more), but it just makes it visually
match a real diff, which at least to me makes a big difference in
readability. Without them, it just looks very "wrong".
I guess I should have taken the filename from each individual entry
(and had one "---" file per parent), but I didn't even bother to try to
see how that works, so this was the simple thing.
With this, doing a
git log --cc --patch-with-stat
looks quite readable, I think. The only nagging issue - as far as I'm
concerned - is that diffstats for merges are pretty questionable the way
they are done now. I suspect it would be better to just have the _first_
diffstat, and always make the merge diffstat be the one for "result
against first parent".

Ok, this was nastier than expected, just because the dependencies between
the different log-printing stuff were absolutely _everywhere_, but here's
a patch that does exactly that.
The patch is not very easy to read, and the "--patch-with-stat" thing is
still broken (it does not call the "show_log()" thing properly for
merges). That's not a new bug. In the new world order it _should_ do
something like
if (rev->logopt)
show_log(rev, rev->logopt, "---\n");
but it doesn't. I haven't looked at the --with-stat logic, so I left it
alone.
That said, this patch removes more lines than it adds, and in particular,
the "cmd_log_wc()" loop is now a very clean:
while ((commit = get_revision(rev)) != NULL) {
log_tree_commit(rev, commit);
free(commit->buffer);
commit->buffer = NULL;
}
so it doesn't get much prettier than this. All the complexity is entirely
hidden in log-tree.c, and any code that needs to flush the log literally
just needs to do the "if (rev->logopt) show_log(...)" incantation.
I had to make the combined_diff() logic take a "struct rev_info" instead
of just a "struct diff_options", but that part is pretty clean.
This does change "git whatchanged" from using "diff-tree" as the commit
descriptor to "commit", and I changed one of the tests to reflect that new
reality. Otherwise everything still passes, and my other tests look fine
too.
