Doc Type:	Bug Fix
Doc Text:	Cause: Previously the behavior of \w and \W symbols in regular expressions were inconsistent with the behavior of [:alnum:] character class. Consequence: Some expressions could cause incorrect match/non-match. Fix: Upstream fix was backported that makes the behavior consistent. Result: Now \w is synonym for [_[:alnum:]] and \W for [^_[:alnum:]].
