Interrupt causing problems for subsequent completions

Thought so...  Sigh, don't have much in the way of details yet.  I did notice
that the signal was being caught by a stack trace that ends like:
      
            strlen         
            modify         [subst.c:2001]
            paramsubst     [subst.c:1538]
            stringsubst    [subst.c:121]
            prefork        [subst.c:70]
            execcmd        [exec.c:1715]

So it looks like compadd is not being interrupted.  But maybe the completion
widget state is somehow messed up.

I have directory /drive2/tools that I attempt to type as "cd /d2/to<TAB>" that
completes properly ( my matching spec has  "r:[^0-9]||[0-9]=**"). But after
interrupting a completion widget, normal completion fails, and it attempts to
do correction, and doesn't expand properly.
