It works if (STRING . RETURN-TYPE) is returned.  But, can we
also change x-get-selection to return that cons?  In my
code, x-selection-value (in x-win.el) calls x-get-selection,
and check if or not the returned string is from the locale
selection by the existence of that text property.
x-selection-value have to know that to suppress another try
with different request-type if the string is from local
selection.

If we can't change x-get-selection, x-get-selection anyway
have to add that text property.  In that case, I think it is
better that x-get-selection-internal itself returns a string
with that text property instead of a cons.
