[boost] [1.34] tiny patch for xpressive

From: Eric Niebler (eric_at_[hidden])
Date: 2007-04-27 12:54:36

Is it too late to get a bug fix in for 1.34? The change is very low risk 
(change a < to <=), but it makes back-references over 9 work as they 
should. The change was applied to HEAD a couple of days ago, and caused 
no problems there. I've tested against the RC branch locally with 
positive results.

Thomas?
