A lot of commands don't make sense outside of major or minor mode, so we 
only have to autoload the modes in those cases.

If 'vc-git-grep' is an independent entry point, it should make sense to 
autoload it. I suppose vc-git is not loaded at the beginning of the 
session because no [Git-controlled] file has been visited yet.

I think I'd also like to advertise 'project-find-regexp' (bound to 'C-x 
p g'). Just in case Alyssa was not aware of it.
