I haven't come so far with releasing, unfortunately, and it will not
happen this weekend, my son takes priority.

Personally, I've no problems with having the PCRE stuff join mainline,
especially since it (as I understand it) will greatly reduce the pain
of having to deal with boost.

A question: how much does the PCRE syntax differ from the boost::regex
syntax?  Is that relevant to know?  Will it impact much on users, for
example when dealing with .mtn-ignore?

Cheers,
Richard
