Yes, I had intended to propose <encoding> as being an unspecified
encoding mechanism (just a placeholder), with the possible exception
of the "binary" encoding.  I definitely do not want to get into
character encoding issues in this SRFI.

I like open-binary-{input,output}-file better.  For completeness, if
we add this we also probably want the binary-port? and character-port?
predicates, though I don't suspect they will be used much any more
than people always check the result of input-port? before reading from
a port.
