Indeed, so programmers should be careful to comment out in a way that makes
it not look like a defun.  That's generally more or less true of code
commented out with M-x comment-region.

Well I didn't say it's obsolete: I said I'd like to declare it obsolete
(but that'll require a few changes).  Note that its current effect is
extremely minor anyway (it only adds "^\\|" to defun-prompt-regexp and
slightly tweaks the way back_comment deals with worst-case scenarios).

Indeed, it *shouldn't*, but it does confuse Emacs, which is why it's
highlighted ;-(.  We should fix it so it doesn't confuse Emacs any more (and
doesn't get highlighted either).
