Thanks, that does look like the right set of changes, with metrics
handled too. The distro packaged version I've got didn't have it, and
I'd found kfish's github rather than the Xiph git.

It'd certainly make sense for it to be included with other Opus tools,
vorbiscomment is a bit of an oddity within vorbis-tools since (hazily
recalled) it supports other stream types than just Vorbis (and a
general comment editor is useful, though it sounds like liboggz has
that covered again).
