Fix a problem that caused the generation of an (almost) empty first page of -mdoc manual pages in troff mode. The problem has been introduced in rev 1.12; apparently ending a line inside a macro definition with \c doesn't behave as Bill expected, and troff was fooled to believe previous output was already pending thus a new page needed to be emitted. Using a troff comment .\" instead of \c seems to solve this, alas the brain^Wnice sed(1) magic needs to be taught to _not_ strip those comments now. I think -stable is not affected by this. 2000-01-27 17:56:41 +00:00			`# $FreeBSD$`
