I actually didn't know about M-;, thanks.
By default, comments starting with ";" are indented to the right
(usually after a line of code), those starting with ";;" are indented
to the code indent location, and those starting with ";;;" are not
moved at all. Also, any comment starting at the very beginning of the
line is left there (regardless of how many semi-colons it starts
with).
The best way to get what you want is to set `comment-add' to 1
locally, by adding to your idlwave-mode-hook in .emacs:
(add-hook 'idlwave-mode-hook
(lambda ()
(set (make-local-variable 'comment-add) 1)))
In fact, I like this so much I'm adding it to the next version of
IDLWAVE. It also affects C-c ; (comment-region -- for the better I
think).
For those of you who want to try M-;, with this fix, on a blank line it
indents and puts in ";; ", on a line with code, it moves to the right
of the code with a ";". Really quite useful. For the curious, M-; calls
`comment-dwim'... "do what I mean" indeed.
Thanks for the suggestion.
