Indeed it already does, and I just meant to clarify that I didn't mean
to throw out the whole test47.

I guess the part I don't understand is why we need it there.
It's called right before loading `tramp.el` but `tramp.el` will
re-execute it anyway when it runs `tramp-register-file-name-handlers`,
so it seems redundant.
