[PATCH] Re: Bug: Callback to widget set with `zle -Fw <widget>` shouldn't change $LASTWIDGET

[Bart Schaefer <schaefer@brasslantern.com>]

Is this good enough, or is there a need to consider that the handler
might delete the previous last widget?  What does/should happen in
that case (or when a widget deletes itself, for that matter)?
