# any-dialog password prompt, rendered with WinForms under
# Windows PowerShell. The text box masks what is typed. Values
# arrive through ANYDIALOG_* environment variables, never as
# part of the script text.
# Exit codes: 0 = answer printed on stdout, 1 = cancelled
# (nothing printed anywhere), 2 = error (message on stderr).
