Tom Lane 173e29aa5d Fix the general case of quantified regex back-references. ... Cases where a back-reference is part of a larger subexpression that is quantified have never worked in Spencer's regex engine, because he used a compile-time transformation that neglected the need to check the back-reference match in iterations before the last one. (That was okay for capturing parens, and we still do it if the regex has *only* capturing parens ... but it's not okay for backrefs.) To make this work properly, we have to add an "iteration" node type to the regex engine's vocabulary of sub-regex nodes. Since this is a moderately large change with a fair risk of introducing new bugs of its own, apply to HEAD only, even though it's a fix for a longstanding bug.		2012-02-24 01:41:03 -05:00
