Hi,
Could someone please fix https://bugs.launchpad.net/slime/+bug/889686 ?
Emacs 24 is picky about comment-column not being an integer and this
breaks quite a few things, including paredit's M-;.
Replacing NIL with eg 40 or any integer value in
(setq comment-column nil)
would be a sensible solution. Not setting the value would also work.
Best,
Tamas
