What's cooking in git.git (Aug 2011, #01; Wed, 3)
--------------------------------------------------

Here are the topics that have been cooking.  Commits prefixed with '-' are
only in 'pu' while commits prefixed with '+' are in 'next'.

There are a few 'fixup!' commits queued in topics still in 'pu', so that
authors have a choice to just say "that fix looks good, squash it in!"
instead of going through an extra round.

I should start making noises about the feature freeze by now, but with a
vacation week in the US early in July, my half-absense during OSCON last
week, and just because it is summer in general, this round is going slower
than planned. Let's shoot for the feature freeze in two weeks and decide
which stragglers to postpone to the next round.

--------------------------------------------------

[Stalled]

* nk/branch-v-abbrev (2011-07-01) 1 commit

The initial "tag --contains" de-pessimization without need for generation
numbers is already in; backburnered.

for different repositories.

so I had to rewind and rebuild 'next' before pushing it out.
