[erlang-patches] erl_tidy option to print to stdout

Besides from cultivating an entire test suite for the erl_tidy module,
which is outside of the scope for the patch, if I were to provide a test
for the addition, I would essentially be testing a simple print function.
Would I not?

Some pointers on what to test would be a great help, otherwise I'm a bit a
loss as to what to test.
