Add initial implementation of having erl_tidy
print to screen instead of writing to the file
provided. The reason for this is that you may want
to have an intermediary step between saving the
tidied file and using the output.
Use-case personally is wanting to integrate
erl_tidy into emacs and tidy buffers, overwriting
the current file is generally not how this works
in emacs with source code tidiers.
