Details:
OSC 8 (Operating System Command 8) is a *nix community-initiated standard for
supporting hyperlinks in terminal emulators within the established syntax of
ISO 6429/ECMA-48.

This isn't strictly a prerequisite for the new .MR (man page cross reference)
feature addition to man(7) I've been rattling my saber about for months, but
it sure would make it easier to test, since at heart I'm a terminal junkie.
That said I'll have to launch of the terminal emulators listed at the URL
above, because my old standby xterm doesn't support this feature yet.
Here's what I think this would look like.
* Add a device control in the 'tty:' space called 'osc8' in parallel with the
current 'sgr' to enable or disable the production of OSC 8 terminal escape
sequences.
* GROFF_NO_SGR would also disable OSC 8 sequences, since its semantics are to
use the legacy output format. This precludes the emission of OSC 8 terminal
escape sequences.
[...time passes...]
This report sat in a browser tab so long that Steffen Nurpsemo, whose
message[1] to the groff mailing list alerted me to the existence of the OSC 8
initiative in the first place has now posted a patch.[2]
So I'll probably base any further design and development on that foundation.
