The MULTIPLE target is unrelated to the question at hand, as it only
provides a more efficient way for clients to request multiple targets of
the same selection at once.  Emacs also implements the MULTIPLE target,
but only for requests from other clients.

The ICCCM doesn't define a specific "list" format, but it does define
separators for several data types.  If you want to respond to a
selection request with a list of file names, then add a selection
converter to `selection-converter-alist' that returns a cons of
`C_STRING' and the encoded file names in a single unibyte string,
separated by NULL bytes.
