[PATCH] Diff-tree-helper take two.
This reworks the diff-tree-helper and show-diff to further make external
diff command interface simpler.
These commands now honor GIT_EXTERNAL_DIFF environment variable which
can point at an arbitrary program that takes 7 parameters:
name file1 file1-sha1 file1-mode file2 file2-sha1 file2-mode
The parameters for an external diff command are as follows:
name this invocation of the command is to emit diff
for the named cache/tree entry.
file1 pathname that holds the contents of the first
file. This can be a file inside the working
tree, or a temporary file created from the blob
object, or /dev/null. The command should not
attempt to unlink it -- the temporary is
unlinked by the caller.
file1-sha1 sha1 hash if file1 is a blob object, or "."
otherwise.
file1-mode mode bits for file1, or "." for a deleted file.
If GIT_EXTERNAL_DIFF environment variable is not set, the
default is to invoke diff with the set of parameters old
show-diff used to use. This built-in implementation honors the
GIT_DIFF_CMD and GIT_DIFF_OPTS environment variables as before.

[PATCH] Introduce diff-tree-helper.
This patch introduces a new program, diff-tree-helper. It reads
output from diff-cache and diff-tree, and produces a patch file.
The diff format customization can be done the same way the
show-diff uses; the same external diff interface introduced by
the previous patch to drive diff from show-diff is used so this
is not surprising.
It is used like the following examples:
$ diff-cache --cached -z <tree> | diff-tree-helper -z -R paths...
$ diff-tree -r -z <tree1> <tree2> | diff-tree-helper -z paths...
- As usual, the use of the -z flag is recommended in the script
to pass NUL-terminated filenames through the pipe between
commands.
- The -R flag is used to generate reverse diff. It does not
matter for diff-tree case, but it is sometimes useful to get
a patch in the desired direction out of diff-cache.
- The paths parameters are used to restrict the paths that
appears in the output. Again this is useful to use with
diff-cache, which, unlike diff-tree, does not take such paths
restriction parameters.

[PATCH] make dotest more amenable to commit message editing
This makes "dotest" a lot nicer to sue, especially for people who were
used to editing the commit comments after-the-fact in BK, which git
doesn't apply.
he syntax is
dotest [-q] mailbox [signoff]
so the command line operates exactly as you're used to. If you supply
the -q it will query before applying (I also added the [a]pply all the
rest option). If the signoff file is absent, no signoff line gets
added.
There's also one addition in this: a checkout-cache line. I added that
for poor saps like me whose laptop takes minutes to checkout a full
build tree, so I can run dotest in a directory with no checked out
files.
