Hm. I stand corrected.

In Emacs 20 it behaves as I described (both for `M-;' and `C-M-q'). I
thought this was broken in Emacs 22, but it seems it was broken in Emacs 21.
;-) 

I never used Emacs 21 (a giant regression compared with Emacs 20, at least
on Windows), and I didn't bother to test it for this - mea culpa.

What is the rationale for this kind of comment indentation? It certainly
doesn't indent the same as `;' or the same as `;;' at the beginning of a
line. Why insert a single space here - what's the rationale? Why move `;;'
ever, relative to the rest of its line?

Anyway, guess it's too late to complain now...

So please consider this a feature request. Please DTRT by not inserting a
space - never move `;;' (except for line indentation, when it starts a
line).
