I though of playing around with CSH_NULL_GLOB like options, but couldn't
get that to work reasonably.  One possibility is to timeout $(...)'s when
they occur inside zle.  However, I think the real bug here is that for some
reason it takes two ^C's to stop it.  Fixing that would just leave the user
with the reponsibility of testing difficult cases (and adding /dev/null on
the end if necessary).
