Fix roff formatting for ->

This was reported in 41276

add missing commas to .Dd fix, pointed out by wiz

OpenBSD uses a custom CVS hack to handle Dd fields ($Mdocdate$) which
we don't have. Replace ".Dd $Mdocdate" with ".Dd Month Day Year" so
that the date comes out right when man pages get built. This will
doubtless need hand conflict resolution whenever these pages are
re-imported.

Note that it would be interesting to have some similar facility for
NetBSD, but I don't think a custom rcs keyword is the right thing --
maybe we can teach groff to parse $Date$
