[vile] Utf-8 word movement broken.

[Ramil Farkhshatov]

Hello.

Recently, I've noticed, that 'next-punctuated-word' in utf-8 cyrillic
text can move cursor inside a word.  'next-word' acts fine.  I couldn't
find exact letters that act like punctuation, but the issue can be
reproduced on these lines (utf-8):
абвгодеёжзийклмнопрстуфхцчшщьъюэюя
АБВГОДЕЁЖЗИЙКЛМНОПРСТУФХЦЧШЩЬЪЮЭЮЯ
ЗЕЛЁНЫЙ
зелёный

It seems that it has been broken by 9.8c patch.
