I realize this.  We use it.  The point is that ~user means "the home directory
of user".  On our network this is always /homes/user which is fixed up by amd
to point to the right place.  If the user concerned is not in the passwd file
on my machine (as many aren't) then ~user as it currently is does not work
even though /homes/user is accessible from my machine.

Following the es principle of making shell mechanisms available, I'd like to
be able to say something like:

fn tilde { return /homes/ ^ $1 }

and have tilde called by es to do the expansion.  People who can use the
default mechanism (ie. all their users are in the passwd file) will not need
to define tilde.  ("tilde" may not be the best name, BTW.)

Not a big deal, but it'd be nice.
