Re: lookaheads in XSLT2 regexes

I didn't realise we were missing \b -- we should add it, if
that's the case.

I think it was omitted deliberately, on the grounds that it's
locale-sensitive. It's defined in Perl as matching "a spot between two
characters that has a \w on one side of it and a \W on the other side of it
(in either order)", where \w matches a "word" character (defined as
"alphanumeric" plus "_"), in which "the list of alphabetic characters
generated by \w is taken from the current locale". That's not an acceptable
definition for our purposes, so it's arguably better to have no definition
at all.
