back to <sys/systm.h>.
2. Remove hard sentence breaks.

mdoc(7) police: Use the new .In macro for #include statements.

Removed whitespace at end-of-line; no content changes. I simply did
cd src/share; find man[1-9] -type f|xargs perl -pi -e 's/[ \t]+$//'

BTW, what editors are the culprits? I'm using vim and it shows
me whitespace at EOL in troff files with a thick blue block...

mdoc(7) police: normalize .Nd.

mdoc(7) police: split punctuation characters + misc fixes.

Fixed bitrot in synopsis. The prototype for panic() was moved to
<sys/param.h>, but the #includes weren't adjusted here.

$Id$ -> $FreeBSD$

Add $Id$, to make it simpler for members of the translation teams to
track.

The $Id$ line is normally at the bottom of the main comment block in the
man page, separated from the rest of the manpage by an empty comment,
like so;

.\" $Id$
.\"

If the immediately preceding comment is a @(#) format ID marker than the
the $Id$ will line up underneath it with no intervening blank lines.
Otherwise, an additional blank line is inserted.
