This patch splits the diff-delta interface into index creation and delta
generation. A wrapper is provided to preserve the diff-delta() call.
This will allow for an optimization in pack-objects.c where the source
object could be fixed and a full window of objects tentatively tried
against
that same source object without recomputing the source index each time.
This patch only restructure things, plus a couple cleanups for good
measure. There is no performance change yet.

This patch adds a Documentation/config.txt file included by git-repo-config
and currently aggregating hopefully all the available git plumbing / core
porcelain configuration variables, as well as briefly describing the format.
It also updates an outdated bit of the example in git-repo-config(1).

Currently, if git-rev-parse encounters an argument that is neither a
recognizable revision name nor the name of an existing file or
directory, and it hasn't encountered a "--" argument, it prints an
error message saying "No such file or directory". This can be
confusing for users, including users of programs such as gitk that
use git-rev-parse, who may then think that they can't ask about the
history of files that no longer exist.
This makes it print a better error message, one that points out the
ambiguity and tells the user what to do to fix it.

This is a fix for a problem reported by Jim Radford where an argument
list somewhere overflows on repositories with lots of tags. In fact
it's now unnecessary to use git-rev-parse since git-rev-list can take
all the arguments that git-rev-parse can. This is inspired by but not
the same as the solutions suggested by Jim Radford and Linus Torvalds.

I hacked it up to teach it the git extended diff headers, made
it not to read the whole patch in the array.
Also, the original program, when arguments are given, ran "diff"
with the given arguments and showed the output from it. Of
course, I changed it to run "git diff" ;-).

Right now it split it into "builtin-log.c" for log-related commands
("log", "show" and "whatchanged"), and "builtin-help.c" for the
informational commands (usage printing and "help" and "version").
This just makes things easier to read, I find.

When $PAGER is set to 'less -i', we used to fail because we
assumed the $PAGER is a command and simply exec'ed it.
Try exec first, and then run it through shell if it fails. This
allows even funkier PAGERs like these ;-):
PAGER='sed -e "s/^/`date`: /" | more'
PAGER='contrib/colordiff.perl | less -RS'

Because we sort the delta window by name-hash and then size,
hitting an object that is too small to consider as a delta base
for the current object does not mean we do not have better
candidate in the window beyond it.

When running "git commit --amend" only to fix the commit log
message without any content change, we mistakenly showed the
git-status output that says "nothing to commit" without
commenting it out.
If you have already run update-index but you want to amend the
top commit, "git commit --amend --only" without any paths should
have worked, because --only means "starting from the base
commit, update-index these paths only to prepare the index to
commit, and perform the commit". However, we refused -o without
paths.

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

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....

* lt/xsha1:
get_tree_entry(): make it available from tree-walk
sha1_name.c: no need to include diff.h; tree-walk.h will do.
sha1_name.c: prepare to make get_tree_entry() reusable from others.
get_sha1() shorthands for blob/tree objects
Several <<< or === or >>> characters at the beginning of a line
is very likely to be leftover conflict markers from a failed
automerge the user resolved incorrectly, so detect them.
As usual, this can be defeated with "git commit --no-verify" if
you really do want to have those files, just like changes that
introduce trailing whitespaces.

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.

.. but don't even bother documenting it. I don't think any normal person
is supposed to ever really care, but it simplifies testing when you want
to use the "git repack" wrapper rather than forcing you to use the core
programs (which already do support the window/depth arguments, of course).

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.
