That name is very close to vim fugitive.

There are only two hard problems in computer science: cache invalidation and naming things (and off-by-one errors)

I know, and it's actually even linked from fugitive's Gitorious page if you click "more…" in the description, but as an Emacs user, I didn't know about fugitive.vim before choosing the name of fugitive, and the name is too awesome to change.
