What's in git.git

It's been two weeks since the last "What's in" update, so here
is the current status.

* The 'master' branch has these since the last announcement.

 - Andy Whitcroft spotted a long-standing bug that prevented 
   send-pack to deal correctly with a ref whose name is longer
   than 45 bytes, where we did not have to have any such limit.

 - Jakub Narebski keeps working on gitweb, with help from Aneesh
   Kumar, Dennis Stosberg, Luben Tuikov, and Martin Waitz.
   There are a lot of clean-ups, including these notables:

   - mechanism to selectively enable or disable features by site
     administrators and repository owners.
   - snapshot and blame are now elective features using the above.
   - gitweb no longer uses temporary files to generate diffs.

 - Jakub also updated a few autoconf stuff.

 - Christian Couder's GIT_TRACE updates.

 - Franck Bui-Huu's clean-up to the code for "format-patch -s".

 - git-daemon acquired a mechanism to selectively enable or
   disable features by site administrators and repository
   owners.

 - pack-objects validates the data it copies from existing pack
   or new-style loose objects.

 - Other small clean-ups, fixes and updates from Johannes Schindelin,
   Jonas Fonseca, Linus Torvalds, Martin Langhoff, Matthias Kestenholz,
   Sergey Vlasov and Shawn Pearce.

 - gitk updates from Paul Mackerras.


* The 'next' branch, in addition, has these.

 - Andy Whitcroft taught send-pack to use git-rev-list --stdin
   so that we do not have to be limited by the number of refs
   exec() command-line can hold.

 - Pasky's Git.pm is on hold; it was discussed and agreed that
   Git.xs layer was a bit premature and is hurting the adoption
   of the entire series.

 - Franck Bui-Huu and Rene Scharfe with a bit help from me added
   git-archive command to unify git-tar-tree/git-zip-tree and
   make them accessible over network.

 - Jeff King rewrote run_status() shell function in git-commit
   and git-status in C.

 - Per requests from the list, "git apply" automatically applies
   binary patches without having to be given --binary flag.

 - Likewise, "git diff --binary" does not give full index line for
   non-binary part of the patch anymore.

 - Pack-objects learned to run rev-list logic internally when
   given --revs parameter; the refs arguments you would normally
   give the upstream rev-list can be fed from its standard
   input, instead of usual list of objects.

 - Pack-objects also knows how to pretend objects that are in
   named packs are unpacked.  This would make easy to update
   repack to incrementally pack loose objects and recent
   "active" pack(s).

 - I have a few patches to upload-pack that would help
   upload-pack when downloader has more roots than the uploader
   has, but this is frozen until I hear real-world feedback.

 - unpack-objects learned a trick not to stop when fed a corrupt
   pack; instead it can make the best effort to recover from
   such an error that was detected.


* The 'pu' branch, in addition, has these.

 - I have a wip to implement index, working tree and zero or
   more trees in parallel but I haven't looked at it for some
   time.
