user() was replying to the user command and then calling login(),
which could send a continuation reply if it fails to chdir to the
user's homedir. Continuation replies must come before the actual
reply; the mis-ordering was causing ftp and ftpd to deadlock. To fix
the bug, invoke login() before reply() so that the continuation reply
comes first.
