Your impatience revealed this bug and your patience located it.  I now
attach a clean patch which also protects the occurrence in window_list_1
although that one doesn't appear so vulnerable - likely because quitting
always eats the maybe_quit from window_list first.  If you don't see any
problems with it within a week or so, I'll install it.
