We can probably do both at the same time, either via makeinfos -D option
and some special macro, or by emitting a machine-generated index, maybe.

How would a flag which has a variable part in the name (like
ffree-line-length-...) get matched?  i.e. what would we need to emit for
it to be linked correctly?  This impacts what the right solution is.

TIA, have a lovely day.
