Add a warning "new sentence, new line".
This does not attempt to pinpoint each and every offender, but
instead tries very hard to avoid false positives: Currently, there
are only two false positives in the whole OpenBSD base system.
Only do this in mdoc(7), not in man(7), because manuals written
in man(7) typically have much worse problems than this.
OK jmc@ on a previous version of the patch
