Last time I checked a "." in a regexp does match \r even if
selective-display is activated, so always \\(.\\|\n\\) matches *any* char.

PS: Furthermore, selective-display is on its way out.
The only code left that uses it (in Emacs-CVS) is in dired-aux.el,
gnus-sum.el, and locate.el, none of which interact with other major modes.
