tramp (2.0.39); backup file naming error (%backup% resulted)

[Peter Woo]

--bug report follows this line--

I use absolute paths for my backup dir alist.  While it works fine with 
ange-ftp alone, it doesn't work when tramp is turned on.

It seems that an invalid backup file name will be returned by the tramp 
file handlers and thus a %backup% file is resulted.

I am now using:
(add-to-list 'backup-directory-alist
            (cons tramp-file-name-regexp nil))

to workaround the problem.

Not sure whether a valid backup file name can be yielded.

Many thanks,
Peter.
