The getpass-implementation we use on Windows isn't at all ideal; it works in raw-mode (as opposed to cooked mode), and as a result does not deal correcly with deletion, arrow-keys etc. Instead, use cooked mode to read a line at the time, allowing the C run-time to process the input properly. Since we set files to be opened in binary-mode by default on Windows, introduce a FORCE_TEXT macro that expands to the "t" modifier that forces the terminal to be opened in text-mode so we do not have to deal with CRLF issues.
