I wonder if these should be API.  It is probably too late to change them, 
since they've existed as API since the late 1990s, but, as far as I can
tell, no one has ever used them (I checked codesearch.google.com 
and koders.com).  They've also never been documented.

But, a patch for documenting these is attached.

Thanks,

Mike
