A bit more experimentation reveals it's just the empty string that's
confusing it. If you put something between the | and the ) it works.
case foo in
foo|'') print Yes
;;
esac
works, also replacing '' by $empty works, but removing it completely doesn't.
I think this might be some fix-up code that got added for the old case
(nothing to do with pipes in that case).
Yes
