I set the coding system to iso-8859-1, set read-quoted-char-radix to 16,
inserted the characters with C-q 80 RET etc., saved the file and the
result was this:

  $ hexdump -C test.bin
  00000000  80 90 85 ff 7f                                    |.....|
  00000005

I inserted ISO8859-1 characters with the knowledge that ISO8859-1 is a
one-to-one mapping from Unicode codepoints to bytes.  This is
effectively how the Unicode codepoints U+0000 to U+00FF are defined, so
I expect that that coding system should work that way.

For the record, for testing I am using a GTK-based Emacs 24.2.92 on X11
(GNU/Linux), running "emacs -Q", my locale is UTF-8, even
keyboard-coding-system is utf-8-unix.  I tried the same with "emacs -Q
-nw" and this also works the same.
