git commit file completion recently broke

Hi,

I'm still investigating, but thought I'd send an email. I recently updated to jch branch, and found that completion for git commit does not work as expected.

If I have a git repository with a modified file in a subdirectiory, then git commit <TAB> produces the name of the subdirectory instead of the file names.

This occurs regardless of where I run the git commit command.

Thanks, Jake
