If I do that, then some other problem happens - I am prompted for:

  "Password for address@hidden"

This is a problem I've reported to this list before, and is to do with
the value of auto-save-file-name-transforms not being quite right.
If you fix the value of auto-save-file-name-transforms and try again,
then the same effect no longer happens.

Before using your 'setq file-name-handler-alist',
buffer-auto-save-file-name's value in the README buffer is
"/tmp/address@hidden"

After using your 'setq file-name-handler-alist',
buffer-auto-save-file-name's value in the README buffer is nil.

Indeed, if I remove your setq for file-name-handler-alist and change
the value of tramp-auto-save-directory to be "/tmp/xyzzy", then
buffer-auto-save-file-name's value in the README buffer is
"/tmp/xyzzy/address@hidden" - indicating that
the value of tramp-auto-save-directory is being used, and that this
isn't just an ange-ftp problem.

I'm talking about auto-save files here, not backup files.  Thanks
anyway though.
