I mean in case you only need to show the channels *or* the standard
layouts, having to parse a single list with a consistent structure is
simpler than having to skip initial or ending lines based on a
possibly changing pattern.
So it seems more natural to me to keep two distinct options for two
different lists (that's similar to what we did with -formats ->
-formats | -codecs | -protocols).
