[groff] mdoc equivalent for man's .TQ?

[Guillem Jover]

Hi!

I've got some man pages using the man package, which I've been
converting to mdoc. But I've been struggling to find an equivalent
for the .TQ macro in mdoc, in the docs (groff and BSDs), and via
search engines.

Is there anything at all within mdoc which I'm missing? How do BSDs
handle things like:

  ,---
  .TP
  .BR \-o ", " \-\-option
  .TQ
  .BR \-a ", " \-\-alias
  Do whatever.
  `---

Perhaps, explictly stating that «-a, --alias» is an alias for
«-o, --option»?

Thanks,
Guillem
