If there's any way to throw an error, that seems better.  I can
imagine someone getting confused by silent failure here.  On the
other hand, since this probably doesn't happen very often, maybe
it's not worth the effort.  I could even see an argument for just
testing for Ctrl+C before each expansion and otherwise leaving it as
is.
