Re: perl-mode problem in C-x ; comment-set-column

[Richard Stallman]

    This has been fixed on the trunk where M-; still looks at subsequent lines
    to try and make sure blocks of comments can be aligned, but where M-;
    doesn't actually align with subsequent lines, only with the previous line.

    Maybe this change should be backported to the 22 branch?

That depends on how simple it is and how sure you are it is right.
