Hello, Somehow some comments (line 10 and 22) in the attached file don't indent correctly. Here are steps to reproduce the problem: 1. Emacs -q 2. (slime-setup '(slime-fancy slime-banner slime-asdf)) 3. M-x slime 4. then C-c M-q on the function in the attached file. Tested on: GNU Emacs 23.1.92.2 (x86_64-apple-darwin10.2.0, Carbon Version 1.6.0 AppKit 1038.25) of 2010-02-03 SLIME: 2010-02-20 Best wishes, Leo
