I don't know what Windows does with this command line. On
Linux you may say a simple

  $ ps aux | grep ssh

and the whole command line is shown. Some programs like
GnuPG offer the facility to pipe the password to $stdin; 
as far as I know BSD Ssh forbids entirely to pass it from
outside.

Maybe host-based authentication is a better solution for
you.
