Backport PR #4144: help_end transformer shouldn't pick up ? in multiline string The help_end() transformer was already tokenizing the line to determine whether the ? was in a comment, so I just extended this to check for multi-line strings as well. Possible for backporting to 1.1, but it's low priority, and this code is fairly sensitive, so it doesn't have to be. Closes gh-4134
