Well, as I've said many, many times on these threads, I feel strongly
that the choice of output format shouldn't for the most part affect
the information which is displayed. Output format should be an
option, and the information to display should be an option, and the
two should be, as far as possible, separate. So what you're
suggesting is the way it works now.
