My current line of thinking is to have a new flag in command struct in
git.c to enable the global --prefix, (c.f. RUN_SETUP | NEED_WORK_TREE)
so we'd have a ALLOW_OUTSIDE_PREFIX flag which can be used to enable
this feature. In case that flag is not set, but a user tries a
--prefix=<somewhere>
we can still

    die("nope, we don't do that");
