OK, you scared me.  The FAILs you see are all expected.  Regex is
simply that buggy.  I looked at all the failing tests once to see
whether there is an easy fix and I haven't found any.

Regex must be rewritten completely and this is one of the things I
plan to do once things settle down with the 2.2 release.  There is
absolutely no hope to use a single piece from the existing
implementation since the most inner code is not prepared for multibyte
characters.
