Hello all,
Common Lisp can use #| and |# to comment a block however its font
locking is usually wrong in Emacs. I wonder if this can be improved?
Thanks.

Don't know: works for me, so I'm not sure what case needs to
be improved.

emacs uses the heuristic that "^(" starts a function.
this mean that a paren in column one which does not start a function will mess
emacs us.
you can add a space before it in comment or backslash in doc string:
(defun f ()
"Doc which contains parens.
\(backslash disappears in the reader but saves emacs)"
code...)
#| add a space before "(defun" to help emacs
(defun f ())
#|

From time to time I have seen code inside #| |# not shown in a comment
face, unfortunately the font locking seems random to me i.e. sometimes
the block is properly font locked after deleting or re-opening the file.
For example:
[-- Attachment #2: emacs-comment.png --]
[-- Type: image/png, Size: 27368 bytes --]
[-- Attachment #3: Type: text/plain, Size: 108 bytes --]
I can get |# to be highlighted in a normal face by deleting or inserting
a blank line in front of it.

Every wondered why those open parens are highlighted in
font-lock-warning face?
