* Revised [tcltest::test] to return errors

        when called with invalid syntax and to accept exactly two arguments
        as documented.  Improved error messages.  [Bug 497446, Patch 513983]
        ***POTENTIAL INCOMPATIBILITY***: Incompatible with previous
        tcltest 2.* releases, found only in alpha releases of Tcl 8.4.
