Inbf8bbe9,getpass.getpass gained
the ability to provide keyboard feedback throughecho_char.

On Unix, line editing shortcuts such as Ctrl+U were previously handled
as the terminal operates in canonical mode (see termios(3)). However,
since keyboard feedback requires to switch to noncanonical mode, this
now results in an inconsistency whengetpass.getpass usesecho_char
as those shortcuts are no more supported. This limitation is specific
to Unix and does not affect Windows users where line editing shortcuts
were never supported.
(cherry picked from commit074f3b2)
