OK, I think I got it. I was able to reproduce it with this additional
detail. The issue is a failing readline command (delete-char with no chars
to delete, in this case) at the end of a multi-key sequences. The problem
is that readline wrongly chooses to back up the key sequence because the
command doesn't return 0. Readline needs to better validate the return code
before backtracking. This will be fixed in the next bash and readline
devel branch pushes.
