I think we can simply delete the line that sets
buffer-file-coding-system: in a unibyte buffer it doesn't matter
anyway.  (And it's wrong to use 'binary' for producing files that will
be processed by programs other than Emacs, because 'binary' spills out
the Emacs internal representation of characters.)
