Seems to me that after doing your damnedest *not* to have the prompt shown,
you don't want it.  `read -q' is documented as always reading from
the terminal, and the prompt as printing on stderr.  I haven't checked
that's what's actually going on, but it's consistent.

I worry a bit about having a hidden file descriptor and FILE * in general:
we should be sure that the shell only uses them for editing or where
explicitly indicated.  But I think it's OK here.
