According to the doc string, the purpose of M-j is this:

    This command is intended for styles where you write a comment per line,
    starting a new comment (and terminating it if necessary) on each line.
    If you want to continue one comment across several lines, use C-j.

Whether that purpose is useful enough that we should continue to have
a command for it, I am not sure.  If it is, we should not forget about it,
If it is not, perhaps we should just eliminate M-j.
