Maybe one can work around it by constructing the regexp differently: instead of allowing any character sequence between "/*" and "*/", one restricts the possible sequences, with the following idea: - any sequence of [^*] is allowed - a * followed by [^/] is allowed The above two can be repeated. I think that avoids backtracking. -- A preposition is not a good thing to end a sentence with.
