Recent BSD su work introduced a failing test. Removed leading space from the assertion that seems to be the culprit.

Addresses multiple issues when using su on freebsd including
* su prompt differs between platforms, so turned that check into a

* not using '-c' after su causes problems, so added that for all
  platforms
* fixed quoting issues due to multiple uses of '-c' introduced by
  the above fix
