On second thought, contrib/ is not quite the right place, because we
typically expect modules there to actually get installed, meaning they
have to have at least some end-user usefulness.  The right place for
a toy PL handler is probably src/test/modules/; compare for example
src/test/modules/test_parser/, which is serving quite the same sort
of purpose as a skeleton text search parser.
