What's cooking in git.git (Jan 2010, #02; Thu, 07)
--------------------------------------------------

Here are the topics that have been cooking.  Commits prefixed with '-' are
only in 'pu' while commits prefixed with '+' are in 'next'.  The ones
marked with '.' do not appear in any of the integration branches, but I am
still holding onto them.

The tip of 'next' has been rebuilt on top of the current 'master'.

* mh/rebase-fixup (2009-12-07) 2 commits
  (merged to 'next' on 2010-01-06 at c4779a7)
 + Add a command "fixup" to rebase --interactive
 + t3404: Use test_commit to set up test repository
 (this branch is used by ns/rebase-auto-squash.)

Initial round of "fixup" action that is similar to "squash" action in
"rebase -i" that excludes the commit log message from follow-up commits
when composing the log message for the updated one.  Expected is a further
improvement to skip opening the editor if a pick is followed only by
"fixup" and no "squash".

  (merged to 'next' on 2010-01-06 at da4e2f5)

 + fast-import: Proper notes tree manipulation

What's the status of the fourth and later patches on this topic?  Overall
it looked reasonable, if I recall correctly what I thought when I reviewed
it last time, and I am tempted to merge it to 'next' soonish.  Please
file complaints before I do so if people have objections.

http://mid.gmane.org/201001051231.43048.johan@herland.net Hold!

'next' soonish.  Please file complaints before I do so if people have
objections.

"git pull" patch needs sq-then-eval fix to protect it from $IFS
but otherwise seemed good.
