do not print "OpenBSD 5.0" but "OpenBSD ports".
While here, remove some noise from the groff build log.
Bump the groff package.
Technically, this changes the contents of all packages that USE_GROFF,
but please refrain from bumping the world: Having "OpenBSD 5.0" in
the footers of some ports manual until they are updated the next time,
or until the next libc bump if they aren't, is not a real problem.
string "OpenBSD ports" suggested and patch ok'ed by sthen@
* Unbreak groff manuals by using tbl(1); reported by pascal@.
* Deal with our Mdocdate cvs keyword; as designed by jmc@ in 2007.
* Use troffrc for OpenBSD config changes; suggested by Werner Lemberg.
* Unbreak the hdtbl examples; from upstream.
* Volume names in man(7) page headers; suggested by Yuri Pankov.
* Update various string tables; coordinated with upstream.
* Add a README explaining local changes; using feedback from pascal@.
* Better description and bump.
ok pascal@, and tested in an i386 bulk build by naddy@, thanks!
