Joey Hess ded2591124 unannex: Clean up use of git commit -a.
This was more complex than would be expected. unannex has to use git commit -a
since it's removing files from git; git commit filelist won't do.

Allow commands to be added to the Git queue that have no associated files,
and run such commands once.
