* module/ice-9/peg.scm (cg-generic-ret): Remove unused for-syntax

  (peg-string-compile): Likewise, and just take the grammar as a syntax
  object.

e2551947dd All r6rs ports are both textual and binary 
* module/rnrs/io/ports.scm (binary-port?): All ports are binary _and_
  textual.  Bytevectors and strings may be written to or read from
  either.

  some sort.

* test-suite/tests/r6rs-ports.test ("8.2.6  Input and output ports"):
  Remove test that binary ports don't have transcoders, because binary
  ports are also textual.
