Your patch is kind of tricky.

`get-free-disk-space' shall not work for remote directories. You bypass
it with the "." directory specification (in fact there is an error in
`get-free-disk-space', which must be fixed).

Before applying your patch to Tramp we shall ensure, that Emacs will
cooperate. That is, we will need a user option which allows
`get-free-disk-space' to work on remote directories. There are also the
variables `directory-free-space-program' and
`directory-free-space-args', which must have proper values on the remote
machine.

Best regards, Michael.
