git-repair (1.20131122) unstable; urgency=low
* Added test mode, which can be used to randomly corrupt test
repositories, in reproducible ways, which allows easy
corruption-driven-development.
* Improve repair code in the case where the index file is corrupt,
and this hides other problems.
* Write a dummy .git/HEAD if the file is missing or corrupt, as
git otherwise will not treat the repository as a git repo.
* Improve fsck code to find badly corrupted objects that crash git fsck
before it can complain about them.
* Fixed crashes on bad file encodings.
* Can now run 10000 tests (git-repair --test -n 10000 --force)
with 0 failures.
