I think you have just described the behaviour that I want and which I
believe most people expect.  Search for all names in the first alternate
location, then in the second, etc., until you get a hit.  But as my simple
example demonstrates that is not what has been implemented (at least for
FIND_LIBRARY) which is search for the first name in all locations in turn,
then continue for the second name, etc., until you get a hit.
