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

  instead of on s-expressions.
  (cg-body): Likewise; though this was a larger refactor.
  (define-nonterm, peg-match): Adapt to peg-sexp-compile calling
  convention change.
  (peg-string-compile): Likewise, and just take the grammar as a syntax
  object.

* doc/ref/sxml.texi:
* doc/ref/texinfo.texi: New files, containing the documentation that was
  previously generated from source and rendered into

hierarchy.png (and .pdf, .eps) were changed to add one node
to the graph, getting them in sync with hierarchy.txt
(and the GOOPS section of the manual).

Also added hierarchy.dot, a file to generate said figure
using graphviz.

* libguile/ports.c (scm_i_set_default_port_encoding): An encoding of
  ASCII is not the same as ISO-8859-1, because it does not allow
  characters above 128.  Fix this.
