Hm, well, HEAD still has the hackery with explicit accounting for
escape sequences.  Could you try it with the patch I showed to unset
TERM and remove that stuff?  (It won't apply exactly to HEAD, but
the diffs are simple enough, or you could revert to 60ab7c80b first.)

Don't worry about it --- even if it was some upgrade glitch, there
was no way to know that in advance.
