skip empty lines

I noticed that supervisor-stdout created a lot of empty rows when I ran
docker logs -f <my_container.

This small change did the trick for me. However, it might be that this kind of filtering is not desirable.

I'm speculating the empty rows arise because:

>>> d = 'data\n\n'.split('\n', 1)
>>> d
['data', '\n']
>>> print('\n'.join(d))
data


>>>

My setup is this:

• Django logs to stdout
• uwsgi runs Django and logs everything to stdout
• supervisor runs nginx and uwsgi and uses supervisor-stdout

If there are blank lines in the data feed, they should be in the output here. Your example shows the correct behavior.
