    In zwei in Release 5.0, Experimental MIT 1.4, FEP 18, on Lisp Machine Jim Morrison (3600):

    There is this problem with autofill-lisp-comments-mode, which is
    that if you insert into the middle of the line, each time a word falls
    off the end, it gets its own line, so you end up with a comment that
    looks like this:

    ;;; Here is a random deduction engine that is good enough for the blocks world.  It is not
    ;;; part
    ;;; of 
    ;;; the
    ;;; planner
    ;;; proper. 

This seems still to be a bug in the latest 243 development system.  I'll
have to check if it is in the newer (249) development system.  If so
I'll have a look at it after the "holiday".
