Extraneous LF when stdout output

[kernc]

Any notebook; the following commands:

$ jupytext --to py example.ipynb
$ diff example.py <(jupytext --to py -o- example.ipynb)
28a29
> 

diff exits non-cleanly as -o- adds an additional newline. I believe end='' or sys.stdout.write()* here might fix it.

print(writes(notebook, ext=ext))

---

* Print function won't work without importing from __future__.

Also this line in tests! 😆

compare(out[:-1], pynb)

Thanks @kernc for the pull request, it is certainly better without the new line!
