ports

[Joe Marshall <jrm@packetclustr.com>]

It seems that read-delimited is expecting an object that answers true to
input-port?  and that the definition of  input-port?  in the
field-reader-package is not the same as that in the user package.  In
particular, it doesn't seem to think that extensible-input-ports are valid
ports to read-delimited.  This seems a like a bug to me, but I really don't
have a clue as to how to fix it.  Anybody else got a clever idea?
