[issue30349] Preparation for advanced set syntax in regular expressions

Sorry, my comment was at best nonsensical gibberish!

I meant to say that this warning message should include the actual regex at fault; otherwise it is hard to fix when the regex in question comes from some data structure like a list; then the line number where the warning occurs is not enough to fix the issue; the code needs to be instrumented first to catch warning which is rather heavy handed to handle a warning.
