bug#38660: ange-ftp.el grammar

[積丹尼 Dan Jacobson]

/usr/share/emacs/26.3/lisp/net/ange-ftp.el.gz grammar problem:

;; For example: if find-file is given a filename of:
;;
;;   /ange@anorman:/tmp/notes
;;
;; then ange-ftp spawns an FTP process, connect to the host 'anorman' as
                                               ^s
;; user 'ange', get the file '/tmp/notes' and pop up a buffer containing the
                   ^s                            ^s
;; contents of that file as if it were on the local filesystem.  If ange-ftp
;; needs a password to connect then it reads one in the echo area.
