What's in git.git

No v1.4.1-rc2 this weekend, as I am expecting a visitor today and will mostly be offline. But we got a dozen or so good fixes and cleanups in "master" so far.

In "next", we have the following being cooked. I expect most of them to be in v1.4.1-rc2 sometime next week. Please report breakage on any of these if you see one.

 - "git rebase --merge" updates by Eric Wong.
 - "git diff -b -w" by Johannes.
 - "git cvsimport" multi-branch fixes by Martin and Johannes.
 - "git diff --color" can be controlled from $GIT_DIR/config.
 - "git merge --squash"; this may not be strictly needed as it
   can be emulated with repeated use of "cherry-pick -n" but it
   might be handy in some workflows.

In "pu", I have queued other bigger changes. I do not think most of them are v1.4.1 material yet.

 - "git format-patch --ignore-already-merged" fixes by
   Johannes; I am hoping to have this in v1.4.1.

 - Perl scripts clean-up and Git.xs by Pasky with a few fixes by
   me; in my mailbox there are several other patches in this
   series not in "pu" that primarily makes more scripts to use
   the new Perl infrastructure.  My feeling is that the series
   needs to be proven to have a sound infrastructure (building,
   testing and installation) on a bit wider platforms before
   starting to consider them for inclusion in "next".  We may be
   able to have the basics from this series in v1.4.1, but am
   still uneasy to convert any important scripts to use this,
   even in "next", at this moment.  Not just yet.

 - built-in "git am" by Lukas; it fails some tests which is not
   a good sign, and as I said in a separate message a few days
   ago, I think it is not worth going this route for something
   high-level as "am", so probably the next round I'd drop the
   last patch from the topic.  The patch to clean up cmd_apply()
   might be worth keeping and merging in "next", depending on
   how the Git.xs effort goes, though.

 - "git diff" option clean-ups by Timo Hirvonen; this is moving
   things in a good direction but as with any intrusive cleanups
   still has some rough edges.  I am hoping we can round them
   off soon to merge it in "next".

 - A new PPC SHA-1 implementation by linux@horizon.com; Linus
   showed that this does not make much difference in real life
   from performance point of view.  If it has other benefits
   (such as code size -- which I do not know how it fares), I am
   willing to merge it as it seems to be correct and does not
   seem to introduce regressions.  But I am not a PPC user so
   somebody needs to push my back on this one.
