Cross-reference the newly added example.9

Update to the 2004 Edition of POSIX.

Bumped document date for the recent changes here.
Fixed bad example of how to start a new sentence.
Added missing punctuation.
Fixed cut-n-paste error in the STANDARDS section.
Mention modern POSIX and C standards.

Grr. Fixup markup on my last commit. Sorry, I'm a little out of practice :)

Sync up ERRORS section with errno.h.

mdoc(7): Use the new feature of the .In macro.

Removed the comment that required all FreeBSD manpages
to have the $FreeBSD$ keyword, as this is now enforced
by the CVSROOT/commit_prep.pl script.

Fold multi-word macro arguments into a single argument
by putting the surrounding double quotes - this speeds
up the -mdoc processing drastically (of course if used
systematically).

Use the new features of -mdoc: exact -width specifiers,
.In macro as an ``.Fd #include'' replacement.

Remove an example of bad sentence breaking style.

Remove whitespace at EOL.

The semantics of the .Os call has been changed. For CURRENT,
this currently implies the default argument of "FreeBSD 5.0".

mdoc.samples(7) is superseded by mdoc(7).

.St -ansiC -> .St -isoC

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

mdoc(7) police: removed history info from the .Os FreeBSD call.

mdoc(7) police: Er macro usage cleanup.

Suggest to use .Lb macro in 2nd/3rd section manpages.

Make share/examples/mdoc and share/misc/mdoc.template internally
consistent, and consistent with mdoc(7) and mdoc.samples(7).

PR: doc/15352, doc/15353

Add $FreeBSD$ lines to these example man pages, along with a note
that says all man pages should contain a FreeBSD revision control
id to make it easier for translation teams.

.Sh AUTHOR -> .Sh AUTHORS.

Use the .An macro in the AUTHOR section.

Update to use the .Rv macro now that I know it exists :-).

Synced with the C example copyright. Cosmetic except for removing
clause 3, which was removed on 1996/08/03 in the C example.

These will appear in 2.2, not 3.0.

Pointed out by: wosch

some stylistic changes... "you name here" and "you name" to "your name"

2.2 Candidate

Update the copyright notices to match our bsd-copyright example.

Add some real example diagnostics to example.[14]

Add all of the possible errno's to example.3.

Show examples of the .Bx (BSD) and .At (AT&T UNIX) macros
in the various HISTORY sections.

Add some .Rs/.Re (used for referencing things other
than man pages) in the SEE ALSO sections.

Correct one minor style point.

Moved these from /usr/share/misc/mdoc to /usr/share/examples/mdoc,
since it seemed like a better place, and the makefiles for
/usr/share/examples didn't need to be fussed with.

The old stuff can be removed from the Attic.
