In 'do_which' (in help.cc) we do

  octave_value val = symbol_table::find_function (name);

and then check

  if (val.is_defined ())

This check seems to fail, so I guess this is parser related.

In this specific case ('warning_ids') I think we should have the
following function:

  function warning_ids ()
    help warning_ids
  endfunction

such that you only have to type 'warning_ids' to get the list, instead
of typing 'help warning_ids'.
