Subject: bug#9246: Scrolling bug with word-wrap in emacs -nw

From: Antoine Levitt <[email-masked]>

How to reproduce:

emacs -nw -Q
(setq word-wrap t)
M-x erc, join a random channel
M-x erc-scrolltobottom-enable
type in a long link (http://longlinkthatgoesoveroneline.com)
type in random lines till window is full
watch all hell break loose (point at top of window, last line not visible)

FWIW, this is an old bug, and probably has nothing to do with bidi.
