If they are different types, they both are in there.  The idea is that the 
receiver can request different formats according to his needs, i.e. plain text, 
HTML, GIF.  There is also a protocol so the owner can be notified about what 
the receiver wants and then produce that format on the fly.  But Emacs only 
pushes strings, so they are replaced.

If we where copying a filename for example, we would in that loop push a 
filename and a string.  String makes sense for a text editor, filename more for 
a filebrowser.
But I think it was intended for "future use".
