I don't see why we need this complexity.  If the user sets the variable,
it's the list of acceptable,  in preferred order.

Are you trying to let people say PREFERRED=foo without thinking about
others, so they get foo if it works, and then the normal order?  I don't
see hordes of unsophisticated users setting this, so I don't see adding
code ot make it slightlye easier for a tiny number of people as a good
thing.
