I pushed your patches, thanks!

Now, I’m slightly worried because now (rnrs io ports) /looks/ complete
but isn’t quite complete.  :-)

For instance,

  - ‘binary-port?’ always returns #t.

  - Transcoder EOL styles are silently ignored.

  - Not all the transcoder error handling modes are supported.

  - Decoding errors are thrown as native Guile exceptions, instead of
    R6RS conditions.

So I think “we” (i.e., you ;-)) should either implement the missing
stuff, or raise an exception, or print a warning when the caller asks
for something that’s not implemented (e.g., EOL style != native), or
document the current shortcomings.

What do you think?
