[ Note: the above code appeared to go well beyond column 70.  I've
"re-unformatted" it to make it fit.  I don't think I've distorted its
meaning.]

There is nothing quite like that at the moment.  However, you can
realign the comments on each line, one after the other.  First, set the
user option comment-column to a sensible value (say, 40), whether by
customize-variable or set-variable, or whatever.  Then do M-; on each
line.  This is described on the page "Comment Commands" of the Emacs
manual.

Another point: this thread would probably be more appropriate on
address@hidden rather than emacs-devel.
