It may be reasonable for "git mv foo bar" to print a helpful message to
the user if foo has un-checked-in changes, similarly to what "git rm" does.

Unlike "git rm", "git mv" could still perform the operation even without
"-f", but the semantics of "git mv" differ enough from plain "mv" that a
short blurb from Git in that case might help.
