Oops, scratch that.  I was confused.

I do not like the magic GIT_WORK_TREE=: which is simply
illogical.  GIT_EDITOR=: made perfect sense (":" is actually a
command that succeeds without doing anything), but ":" does not
have anything to do with "there is no such path".

I was tempted to suggest GIT_WORK_TREE=/dev/null because that is
what "diff" uses to mark "this does not even exist", but that
feels dirty.
