I can see two ways to do this: pass an argument somehow to revset._stringmatcher function to switch off 're:' prefix check, or just replacing '\(\s+re:' with '(literal:re:' in the query string. The first methods seems more robust of course. Am I correct here?

sounds right to me. I can't think of other things that take regexps at
the moment.
