If the batch says

  cmd /c echo arg1 = %1, arg2 = %2

i.e. invokes cmd.exe from the batch file, does the test still fail?

If it still fails, I think making the test more tolerant of the
trailing whitespace is IMO a better alternative than letting it fail.
After all, that trailing space is not what we are testing there.
