Subject: Re: Display feedback while typing password in terminal.
"Why is it not seeing my typing?" is one of the most frequest questions I
get from newbies though. Makes me wonder if it would break anything for
anyone if it were changes upstream to echo each input character with an
asterisk. Any ideas if it would? Would it make a difference if passwd or
getpass() were changed> Would it be a security issue in any way?
