Symptoms:
emacs -q --no-site-file &
M-x emacs-lisp-mode
M-x font-lock-mode
Insert into the (current) buffer (i.e. *scratch*)
(define-key 'cvs-mode-map "
" 'cvs-mode-find-file)
The second argument of define-key() is C-m, inserted with C-q C-m.
Now type
C-a ;
The comment will be highlighted as such until after ^M. Any text that
is inserted after it is coloured like a string, until the next double
quote, until after a number of lines (consisting of a mix of comments,
blank lines and Lisp code), or until the end of the buffer.
The expected behaviour is that only ^M is considered to be the string.
It seems that ^M is considered as a line break (incorrectly in this case).
