It is good that you could implement this mostly in Lisp;
that makes it easier to customize and adapt.
Thanks for improving the doc strings.

Could you put a blank line between a function definition
and the preceding comment?


If the user drops an icon representing a file into a Dired buffer,
I think it should rename or copy the file into that directory.
That is what drag-and-drop was used for originally on
the Mac: to move files between directories.  But I don't
see any code here to do rename or copy.

If we know the target is a dired buffer, we can then accept the
action that the source sends us (XdndActionCopy or XdndActionMove)
instead of always using XdndActionPrivate and to the right thing
for each action.

Does the current protocol handle dragging and dropping of files in any
way?  I don't see anything in x-dnd-known-types for files.

The types text/uri-list, text/x-moz-url, FILE_NAME and _NETSCAPE_URL all
can have file:// URLs. text/uri-list is the one XDND and the freedesktop
organization wants everybody to use.  text/x-moz-url is used by mozilla
and newer netscape.  FILE_NAME is used by the OpenWindows protocol (and
maybe older programs that don't do XDND, but Motif or OpenWindows),
_NETSCAPE_URL are older netscape (4.x and older).

So the file code is just handling the file:/// URLs.
