^M is only a comment ender when selective-display is active.  So only
set its syntax to comment-end when selective-display is active.
Better yet: stop supporting selective-display.

It does: it maps them all to ^J.
^M in a buffer is not a line-ender (except for the oddball case of
selective-display which is a feature that needs to die).
