Disabling display of passwords in FTP/FTPS debug output

[Tilo.Muetze]

Hi Alexander, Hi list,
we are using lftp for the protocols SFTP, FTPS and FTP. When using a debug 
level >=5 the FTP/FTPS password is displayed in the lftp output, see below:
---> USER user1
<--- 331 Send password please
---> PASS test1
<--- 230 User logged in, proceed

This differs from SFTP, where the password is hidden, in any case:
<--- us...@xxx.xxx.xxx.xxx's<mailto:us...@xxx.xxx.xxx.xxx's> password: XXXX

We would like to vote for a solution where the password is hidden anytime, also 
if debug level is >=5 and protocol is FTP/FTPS. What do you think?

Thanks a lot,
Tilo
