Issue #1889 has been updated by Yui NARUSE. > > RE.txt is for original Oniguruma, not for Ruby 1.9's regexp. > > We may need our own document. > > Absolutely. :-) Can I open a ticket? Yes, please. I think, this change is not a bugfix. But whether backport a patch or not is depend on stable maintainer. If you want to backport, open a ticket on 1.9.1 as backport and persuade yugui. ---------------------------------------- http://redmine.ruby-lang.org/issues/show/1889 ---------------------------------------- http://redmine.ruby-lang.org
