re overriding the meaning of ~:  in the future, yes.  right now, maybe not,
because a serious amount of code would have to be reorganized to support it.
(~ is done in the globber, the globber runs with gcblocked, and you can't
run code with the garbage collector off.)

for now, if you really want ~user to always turn into /foo/user, hack the
globber.  (glob.c, in dirmatch() and glob1()).

when this does become a redefinable function, it will probably be called %home.
