I've checked the Tramp code. And indeed, Tramp seems to be
responsible. It adds the function `tramp-set-auto-save´ to
`find-file-hooks´, independant of method being "ftp" or something
else.

Hmm. As workaround it seems to be sufficient to set
`auto-save-default´ to nil - but this would disable auto save in
general. Looks like there is a Tramp bug, indeed.

I copy this message to Kai, because I'm not familiar enough with
Tramp's auto-save mechanics. Maybe it is sufficient to clean up
`find-file-hooks´ locally when calling Ange-FTP, but I feel there must
be a more elegant solution.
