This release seems to have a serious performance regression when using
diff-mode on large diffs with long lines (e.g. created by comparing the
logs of two compilations), especially when combined with
toggle-truncate-lines.  Emacs becomes unresponsive with 100% CPU load
when scrolling fast, sometimes for several seconds.  The CPU time seems
to be spent in redisplay().

Achim.
