        Well, I have no problem with that: Gnus uses different Summary
        buffers for different groups, M-x mml-preview keeps creating new
        buffers even if called for the very same message buffer, and
        well, find-file isn’t constrained to a single buffer, either.

        Yes, I know: I’ve already patched the code.  (I’ve tried to
        contact assign at gnu dot org for copyright disclaimer papers,
        but haven’t received any reply so far.  And now I guess I’d have
        to wait to the next year due to the holidays, anyway.)

        Please note that eww-setup-buffer is called from the buffer
        filled by url-retrieve, and /not/ from one of the EWW buffers.
        I see no obvious way for it to deduce from which buffer the
        original command (say, M-x eww) was called so to get back there.
