fileno is a pretty standard part of any UNIX API, but if you'd like to
suggest new wording I'd be happy to include it.  There are also new
'binmode.o', 'textmode.o', and 'automode.o' object files available for
changing the defaults on a per-binary basis.  automode.o (probably
misnamed) changes the default to 'read text'/'write binary'.
