(tramp-parse-rhosts, tramp-parse-shosts)
(tramp-parse-hosts, tramp-parse-passwd): Apply `push' but
`add-to-list' for performance reasons.
(tramp-get-completion-user-host): Return `nil' in case both `user'
and 'host' are empty (not necessarily `nil'.
(tramp-parse-netrc, tramp-parse-netrc-group): New functions.
(tramp-user-regexp): " \t" are not user regexp characters.
(tramp-completion-handle-file-name-all-completions): Remove
Ange-FTP cmpletion. It has a bug not handling the "/ftp:" prefix
completely, and it returns local completions as well.
(tramp-completion-function-alist-ftp): New constant.
(tramp-completion-function-alist): Add completion function for
"ftp".
