I think, you could iterate over all tokens located from after the WS->getCond()->getLocEnd(), but before the WS->getBody()->getLocStart(). If the first non-comment and non-whitespace token you find is not a closing parenthesis, you can bail out, because something weird is going on. I don't think you'll need to handle macros here.

This is not exactly true, but it doesn't matter for our problem.
