Windows and Unix platforms have behaved differently in this regard up until
19. On Unix stderr has been redirected to stdout, but on Windows it has not
been. In Erlang/OTP 19.0 I changed it so that both Unix and Windows behave
the same way, i.e. they both redirect stderr to stdout for os:cmd. It would
seem that I have forgotten to mention this incompatibility in the release
notes.
