What's in git.git (stable)

[Junio C Hamano <junkio@cox.net>]

Together with fixes to pack-objects mode bits gotcha that caused
quite a traffic on the list this morning, and crlf conversion
bug from Alex, I've fast-tracked a few topics to 'master' tonight:

 - Nico's progress meter clean-up.
 - My custom diff driver in gitattributes series.

By "fast-track", I mean there might still be bugs in the code
but there do not seem to be anything contentious in the design,
and I trust the people who can fix possible breakages are
responsive.  I think "ident" attribute to expand "$ident$" in
blobs is probably less controversial as it is a stateless
transformation, but I left it out for now.

The tip of 'master' tonight is v1.5.2-rc0.  I am reasonably sure
that I have missed a few topics that we saw/reviewed patches for
the past several days.  Please do not get discouraged as I have
not necessarily rejected them; I was just busy whipping v1.5.1.2
and the 'master' branch into shape tonight.  Please discuss the
patches that are missing from tonight's 'master' for possible
inclusion in the coming few days, and then let's declare feature
freeze by the end of the week with v1.5.2-rc1.  After that, the
usual rules for stabilization period applies (no new features,
only fixes including documentation updates).
