Re: regexp character class locale awareness patch

According to POSIX -regex (7)-, standard character class are:
             alnum       digit       punct             alpha       graph       space             blank       lower
upper             cntrl       print       xdigi
 

Many of that classes are different in different locales, and currently
all work as if the localization were C. Many of those tests have
multibyte issues, however with the patch postgres will work for
one-byte encondings, which is better than nothing. If someone
(Tatsuo?) gives some advice I will work in the multibyte version.

Yeah, that should work. You may also remove include/regex/cclass.h
since it will not be used any more.

This is not the case.
