When I think that a version committed by myself r90650 (marked as new) is fully obsolete and already replaced in my other commit r90684 (marked as fixed) in order to save code reviewers' time, here are my questions: 1. shall I revert the 90650 from SVN ? 2. how exactly, and what would be meaingful comment ? 3. or can I do anything else which is of help in this case? I need to ask here, because I could not find clear instructions or conventions for such cases on http://www.mediawiki.org/wiki/Code_review_guide and http://www.mediawiki.org/wiki/Subversion T.
