Unfortunatly ``--'' already has certain semantics.  Detecting it 
wouldn't be sufficient.  Consider things like:

	--argument-expected --
	-- --poor-programe-name-choice --poor-core-file-choice
	gdb --args -- gdb --args -- program arg arg

Tom's --args -- is somewhat grotesque but at least it is well defined. 
Something like:

	gdb --- gdb --- program arg arg

might be possible but it is really sugar for ``--args --''.
