"Display all XXX possibilities" bug - bash, readline or something else?

[dav7]

I was going about my business one day when I executed the following
steps in order without meaning to:

1. Caused the "Display all XXX possibilities? (y or n)" message to
appear
2. Resized the window
3. Noticed that the message disappeared, but the acceptance of y or n
(and only y or n, save ^C of course) was still in effect.

So, I first started out by posting a message to my distro's forum, and
got a pile of confirmations with a bunch of different terminals. The
post is here: http://bbs.archlinux.org/viewtopic.php?pid=429633

I'd say this was an official bug, and needs to be fixed.
