Here's an even more minimal test-case:
emacs -Q
(setq emacs-lisp-docstring-fill-column 30)
(insert "\"a word, another word and more :bar\"")
M-q
gives a break of:
| a word, another word and
| more :bar
whereas one would expect
| a word, another word and more
| :bar
The problem appears to be in the regexp used to define
paragraph-start in lisp-fill-paragraph:
...
(let ((paragraph-start (concat paragraph-start
"\\|\\s-*\\([(;:\"]\\|`(\\|#'(\\)"))
...
Removing the colon leads to "expected" line breaking.
FWIW, the colon was introduced by this commit:
commit cd3f5084abdd59a8392cedee90ddbaa096d61d55
Author: Dave Love <fx@gnu.org>
Date: Wed Mar 18 16:02:37 1998 +0000
(lisp-fill-paragraph): Adjust
paragraph-start in default filling case so that filling doc
strings works.
Cheers,
Lawrence
