What's in git.git (stable)

I thought we were pretty in good shape and in a nice and quiet freeze period.

Until a few days ago.

Then suddenly, flurry of activity happened. A few performance issues were raised and fixed:

 * "git-status" on a huge tree was way suboptimal and found to
   have unnecessary O(n^2) codepath.  Fixing this also sped up
   "git-diff --cached";
 * "git-commit paths..." had a few other bottlenecks.  "git-add
   --stdin" was one of them;
 * In addition, Linus optimized all three cases of "git
   read-tree" that had the same inefficiency;
 * "git-bundle create" had a stupid "one-byte-at-a-time" loop
   that was unnecessary.

Also one of the new features in 1.5.3, GIT_WORK_TREE, was found to be not-quite-ready. I think the few commits during the last couple of days should finally make it ready.

I have resisted merging any new features that were not present in 1.5.3-rc1, but it appears that we would need to have a few more -rc rounds before the final _anyway_, so I went into a merge-binge. A couple of well done topics from the next branch are now in master:

    * Carlos's "builtin tag" series;
    * David's "format documentation in info format as well" series;

Expect the tip of 'master' to be tagged v1.5.3-rc5 and let's hope it to be the last -rc before 1.5.3 final.

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