Subject: [PATCH 1/1] hcoop-git-maint: Improve detection of bad permissions.

 - Fix bug where bogus symlink loop would be created.

 - Iterate through /var/cache/git on the second run, not everyone's
   homedir regardless of whether they're using git.

 - Check AFS permissions at a deeper level.  Skip object and refs
   directories because they might take a while.
