Well, any such output would presumably be on a different line and
thus distinguishable from the SSL property; plus, it'd be impossible
for both forms to show up in the same connection.

However, how about writing "SSL compression: on" versus writing
nothing? That avoids doubt about what it means. I don't buy
Michael's argument that this is ambiguous, either.
