PCRE 8.3.4-RC1.

The two patterns below do not match identically. [\s] always matches VT
but \s only if the current locale defines VT as space.

/[\s]+/
     > \x09\x0a\x0c\x0d\x0b<

/\s+/
     > \x09\x0a\x0c\x0d\x0b<

I believe that according to SVN 1363, ChangeLog entry 18, \s should
always match VT even if the current locale does not define it as such.
