  * Rename all the Xtract combinators to match standard combinator names.
  Ditches the idea of name-mangling the original combinators to their
  double-filter equivalents by surrounding alphabetic names with leading
  and trailing 'o', or doubling operator symbols.  Too arbitrary and
  unreadable.  Now the combinators have exactly the same names, and they
  are disambiguated by the standard mechanism of module qualification.
