Right answer, wrong logic.
First we create a subshell whose stdout _and_ stderr have been redirected
to the file `error'.  _In_ the subshell we execute `program_name' with its
stdout redirected to the file `output'; we don't mess with its stderr, so
that'll still be connected to `error'.  The result of it all is stdout
going to `output' and _only_ stderr going to `error'.  QED
