Yes, I see in you rc2+2 diff it was added into that.  I will have to
allocate a new number for that fix though, as technically it's a
different feature than variable-length look-behind.

For now I'm having a hard time merging your diffs in with my code base.
 Lots and lots of conflicts, alas.

BTW, what UID did you try to register under at Launchpad?  Maybe I can
see if it's registered but just forgetting to send you e-mail.
