backward-word: WTF?
You won't believe this one. Start up `xemacs -vanilla', type "a b"
(no quotes) into *scratch*, then press `M-b'. For me the point ends
up at the beginning of line instead of at the beginning of "b".
Somebody seriously fucked up scan_words(), which a potential to damage
XEmacs seriously. The `#ifdef MULE' code looks especially suspicious
(I still run with Mule). Please be more careful when changing code.
