description:
cvs.1 & cvs.texinfo: add a missing section documenting the "tag" and
"rtag" commands. This is taken mostly from the upstream project's
cvs.texinfo revisions 1.686 and 1.687. Additionally, I've reflected
NetBSD's local changes to log "tag" as well as "rtag" in history, and
to require admin privileges for destructive tagging commands. This
addresses PR bin/33877.

+Use \fBtag\fR to assign symbolic tags to the revisions of files
+checked out into your sandbox.  The tags are applied immediately
+to the repository, with the revision numbers to attach the tag
+to supplied implicitly by the \fBcvs\fR records of your working files.
+.SP
+\fBrtag\fR works similarly, but does not need a sandbox to operate
+in, requiring an explicitly supplied tag or date instead (or assuming
+the tip of the trunk when one is not supplied explicitly).  \fBcvs\fR
+uses this preexisting tag or date to determine which revisions of
+files in the repository to attach the new symbolic tag to.
+.SP
+The symbolic tags are meant to permanently record which
+revisions of which files were used for some purpose.  The \fBcheckout\fR
+and \fBupdate\fR commands allow you to extract an exact
+copy of a tagged release at any time in the future,
+regardless of whether files have been changed, added,
+or removed on the trunk or other branches since the release was tagged.
+For more, see node `Branching and merging\(aq in the CVS manual.
+.SP
+These commands may also be used to delete a symbolic tag,
+or to create a branch.  See the options section below.
