Original text:
For a whole set of track titles, I corrected them (auto edits) and of course made the open edits fail. It would be nice if, before hitting submit, there was a warning on that page that said "Hey! You dummy! You're going to make these edits fail if you go through with this. Why don't you check if they have already corrected the problem before going through with these changes?"
