Correctly _pipe_ child process's stderr to elm-test's stderr
Correctly _pipe_ child process's stderr to elm-test's stderr

The 'pipe' option actually _captures_ the child process's stderr
as a property on the process as a stream; it won't be piped to
the parent process's stderr unless you explicitly write code to
do so.
