In GNU Emacs 19.25.94.4 (sparc-sun-solaris2.3, X toolkit) of Fri Aug 19 1994 on prometheus

Setting selective-display to t (replace "^M.*" with "...") makes the
line number in the modeline wrong for modes like hide-ifdefs which
replace newlines with ^Ms.  It counts all the ^M'ed lines as one
line.  This bug was not in earlier emacs 19 versions, like 19.21.

I know it's strictly true that once the \ns are replaced with ^M the
whole thing *is* one line, but it should give the impression that
many lines are being moved over.

I'm not sure whether this should be recorded as a selective-display
bug or if there's really some other method hide-ifdefs should be using
instead of (setq selective-display t) to hide its ifdefed out text.
