Playing with zle widget gives unexpected exit

["Bart Schaefer" <schaefer@xxxxxxxxxxxxxxxxxxxxxxx>]

I can make this happen repeatedly, but not by any particular series of
actions.  I'm playing with a zle widget function fiddles with $CURSOR
and then calls "zle .transpose-words", and the exit seems to happen only
after I've removed and re-autoloaded the function definition, but it
doesn't happen *every* time I remove and re-autoload the definition.
