lftp "open -u user,pass url" regressed?

[Paul Lew]

I have been using the following format:

    > lftp
    lftp> open -u user,pass sftp://host/dir

without problem.  But now this format no long works, instead, I
got:

    lftp> open -u user,pass sftp://host/dir
    cd: Login failed: Password required

Seems this format is no longer accepted.  However, the:

    lftp> open sftp://user:[EMAIL PROTECTED]/dir

works.  Is the function regressed or the man page need update?

Thanks in advance.
