Your patch looks OK to me. Loading gnus.el.gz via ssh works, because
tramp-ssh preserves the suffix when applying `file-local-copy'. You get
the same result for `ange-ftp-file-local-copy' with your patch.

Maybe we shall extend the docstring of `file-local-copy', saying that
suffixes must be preserved.

This is related to Bug#1529 and Bug#5705. Now, after Tramp 2.1.19 has
been released, I plan to reorganize Tramp's packages and their load
dependencies. Shall be fixed then.
