Commit d543d59cf0d90264aa84ac49b7f21c6a603d5d3a
2014-03-28T10:42:38
Add some funny options for debugging status This allows you to use a --repeat option to run status over and over and see how the output changes as you make local directory changes without reopening the git_repository object each time. Also, adds a flag to explicitly list the submodules before status.
