What's in git.git

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

* The 'maint' branch is now for post 1.4.3 fixes.  It currently
  contains these:

   Nguyễn Thái Ngọc Duy (2):
      Reject hexstring longer than 40-bytes in get_short_sha1()
      Add revspec documentation for ':path', ':[0-3]:path' and git-describe

   Nicolas Pitre (1):
      reduce delta head inflated size


* The 'master' branch has produced 1.4.3 release today.  I've
  merged the 'maint' fixes and the first wave of what have been
  cooking in "next".

   Andy Whitcroft (1):
      add proper dependancies on the xdiff source

      fetch: Misc output cleanup

   Sasha Khapyorsky (1):
      git-svnimport.perl: copying directory from original SVN place


* The 'next' branch, in addition, has these.  Roughly speaking,
  there are two and half big topics:

  (1) Nico's delta-base-offset encoding;

  (2) Linus's packed-refs and related changes;

  (3) my blame --porcelain and its use in gitweb;

  When the dust settles after the first wave I pushed out
  tonight, I'd merge delta-base-offset stuff as the second wave,
  and then hopefully packed-refs stuff after that.  I suspect
  there still remains breakage around ref-log I need to fix in
  the latter topic.
