Are we sure on this one? I don't think a WMFW is required to
include an INFO/NAME block so it is now possible for this to not
get printed. Granted I have not seen one that doesn't include
at least one of these blocks but it isn't required. I think I
would lean towards keening the separate print personally.

Thanks,
