05a5e5d6d0 toplevel vars added by syntax expansion are unbound
* module/ice-9/psyntax.scm (chi-top): When adding to the toplevel
  environment at compile-time, default to undefined variables, not
  variables defined to #f.

* module/ice-9/psyntax-pp.scm: Regenerate.

* module/ice-9/boot-9.scm (module-add!): Add a new pre-modules version
  of this function, so we can add variables the environment, not just
  values.
  (module-define!): Use module-add!.

6a07a06118 Do not apply inf?' or nan?' to strings
* module/ice-9/format.scm (format): Test to make sure an argument is a
  number before applying `inf?' and `nan?' to it.  Formerly, format
  would call `inf?' and `nan?' on arguments that might be either a
  number or a string, although those predicates should ideally throw an
  exception when applied to non-number objects.

8390dac023 more format tweaks
* module/ice-9/format.scm (format): Move the port and output-col to let*

  string.
