I committed this patch based on an OK that tb@ sent me privately
and also installed it on man.openbsd.org, so now when you write

  .%R RFC 1149

in a manual page (as you always did, no need to learn anything new),
you get a clickable hyperlink, for example look at:

  https://man.openbsd.org/ssh-keygen#SEE_ALSO
  https://man.openbsd.org/utf8.7#STANDARDS
  https://man.openbsd.org/rpki-client#STANDARDS

Yours,
  Ingo


P.S.
I also applied the same to -T markdown output as to -T html output,
such that people who maintain portable software projects outside
OpenBSD and keep their code on github or similar markdown-using
platforms also get the same kind of clickable hyperlinks there:

 $ man -T markdown utf8
[...]
