In code it is called "prefix". But I have to ask: So what? Are you
suggesting GIT_PREFIX? User expectation is probably more tied to CWD,
unless a user knows "rev-parse --show-prefix". I don't care about the
name, and GIT_PREFIX may be more systematic.

A more important point is the prefix-less case (i.e. we are in topdir):
Should GIT_YOUNAMEIT be empty then? I would say yes (just like
"rev-parse --show-prefix"), Duy said no. We need a third vote :)

Also, we may want to scrap this altogether and do !!-aliases instead
(without chdir).
