The warning_ids.m file should be present in the scripts/miscellaneous
directory.

It is not really a function.  It just contains a doc string.  So

  help warning_ids

should work.  It used to, but now I all see is

  octave:1> help warning_ids
  `warning_ids' is a  function



  Additional help for built-in functions and operators is
  available in the on-line version of the manual.  Use the command
  `doc <topic>' to search the manual index.

  Help and information about Octave is also available on the WWW
  at http://www.octave.org and via the help at octave.org
  mailing list.

so for some reason the new help system is not noticing that there is a
doc string in this file.  Does it rely on the parser grabbing the help
text?  Maybe some recent change I made to the parser broke this.

I see that it does recognize the doc string if there is at least a
statement in the file, but for compatibility with Matlab, Octave
should be able to handle .m files that contain doc strings in a
comment and nothing else.
