Hmm.  Now, how does "git-blame" tell if there is usable git-gui
installed with it?  Will we have "git-gui --list-features"?

It can run `git gui version` and check to see that it is >= 0.7.3.

This is only minor nuisance, but can we do something about this?

 $ git gui --version
 Application initialization failed: no display name and no $DISPLAY environment variable

I know it is from wish, not you, so I wouldn't insist, though.
