* Editor variables can now define a procedure that will "normalize"

  their values.  The DEFINE-VARIABLE has been extended to allow the
  specification of this normalization procedure to follow the
  specification of a validity test.

* New procedure VARIABLE-LOCAL-VALUE? is true iff the given variable
  is locally bound in the given buffer.

* Procedure VARIABLE-VALUE-VALID? has been eliminated.
