* module/rnrs/io/ports.scm (display): Implement as an exception-converting wrapper around Guile's core display. * module/rnrs/io/simple.scm: Don't export Guile's corresponding core procedures, but use `(rnrs io ports)' instead. This way, we get the conditions required by R6RS raised. * doc/ref/r6rs.texi (rnrs io simple): Mention that these procedures are supposed to raise R6RS conditions.
