Title: DRY: comment/uncomment/toggle-comment

BTW in 6cf6d31b37dfaf52c4f0a48f97c32114b60d729a Boryslav modified a bunch of functions to multimethods in order to get rid of some warnings by passing nil as a default parameter. I think this way we just stash away the warnings without properly resolving them. IMO it would be better to leave the warnings displayed until someone gets irritated enough (as I got) and fixes the warnings properly, just as I did in this patch.
