If I start a new Emacs and do the same, the echo area says "M-:-", so... something I have eval-ed in this session has changed the behaviour? `read-char' still points to the built-in function... > I don't think it's a bug, though: that's how character echoing works > in Emacs.

I think this behaviour should be noted in the doc string, at least. The only thing it says about PROMPT is -- If the optional argument PROMPT is non-nil, display that as a prompt. -- and noting the nil/"" behaviour should be simple enough. (I guess the changes should be to the doc strings of read-event/read-char/read-char-exclusive.) -- (domestic pets only, the antidote for overdose, milk.) bloggy blog: http://lars.ingebrigtsen.no
