I don't know exactly about the comment-ending behavior of M-j.
Maybe Martin was thinking o cases where you want

        (* blabla
         * blibli *)

But my main beef with M-j is that it doesn't handle the fill-prefix.
I often would like it for M-j to turn

        prefix> hello! there
into
        prefix> hello
        prefix> there

I.e. I think that M-j should force some kind of auto-fill-at-point
(i.e. cut the line at point as if the line was being cut because of auto-fill).
