  at this point, i would throw out *all* of this and, rather than try
to cram disambiguation into the bullet lists currently in that man
page, just break it out into its own section, where it can be
explained properly and comprehensively.

  the reason this has gotten so chaotic is that we're trying to
preserve the structure that is in that man page, when it should just
be tossed and rewritten to give "--" and disambiguation the section it
deserves.
