OK, OK, final definition of is_string():

  if sys.hexversion >= 0x02020000:    # Python 2.2 or greater
      def isstring (x):
          return isinstance(x, types.StringTypes)
  else:
      if hasattr(types, 'UnicodeType'):
          _string_types = (types.StringType, types.UnicodeType)
      else:
          _string_types = (types.StringType,)

      def isstring (x):
          return type(x) in _string_types

The fact that this caused the most response indicates that my patch is
good.  I'll go check it in now.  One more big change for Quixote 0.5!
