Irrelevant. You can achieve the same kind of confusion with `emacs
-font'. :-)

That's true as a definition, and incorrect as a matter of fact in
multibyte buffers. Unless Emacs enforces "no-conversion is unibyte",
"no-conversion" should die, and split its estate between "raw-text"
(where newline conventions are meaningful) and "binary" (or
"raw-bytes") for non-text files.

Binary isn't a text encoding, and therefore it's entirely appropriate
that it lack a mnemonic meaning in the context of text encoding.<wink>
In any case, only Emacs maintainers should ever need to care about
the representational transformations performed by coding systems, and
they all do know what binary means. Everybody else just needs to know
the magic spell that turns mojibake into language; even if they did
know about representations, they can't do anything about it. (I guess
that's not strictly so in Emacs, but it should be. ;-)
