Yes, that's what I was thinking of.

I never use octal myself and have configured Emacs to display raw bytes
as hex, so I agree with the first assertion.  But the latter isn't a
very friendly caricature.  The reason we don't remove all the octal
stuff from Emacs is that it'd annoy a significant number of people.

Making a format-spec thing for `C-x =' would be fine by me.

I don't understand the aggression here, though.
