[2/4] What's not in 1.5.2 (will cook in next)

These have been cooking in 'pu'; will be in 'next' after 1.5.2 happens.

*  db/remote (Tue May 15 22:50:19 2007 -0400) 5 commits
 . Update local tracking refs when pushing
 . Add handlers for fetch-side configuration of remotes.
 . Move refspec parser from connect.c and cache.h to remote.{c,h}
 . Move remote parsing into a library file out of builtin-push.
 + git-update-ref: add --no-deref option for overwriting/detaching
   ref

This was rebased on to Sven's change to lock_any_ref_for_update();

*  dh/repack (Sun May 13 12:47:09 2007 -0700) 9 commits
 . git-repack --max-pack-size: add option parsing to enable feature
 . git-repack --max-pack-size: split packs as asked by
   write_{object,one}()
 . git-repack --max-pack-size: write_{object,one}() respect pack
   limit
 . git-repack --max-pack-size: new file statics and code
   restructuring
 . Alter sha1close() 3rd argument to request flush only
 + Custom compression levels for objects and packs
 + deprecate the new loose object header format
 + make "repack -f" imply "pack-objects --no-reuse-object"
 + allow for undeltified objects not to be reused

This follows the "custom compression levels" series from the same author.
