Parser fails if comments are used in requirements.txt

[underyx]

The requirements.txt starts with:

#
# This file is autogenerated by pip-compile
# To update, run:
#
#    pip-compile --output-file requirements.txt requirements.in
#

argparse==1.2.1

The traceback is:

For now, it's possible to downgrade to tox-battery~=0.2.0 to work around this.

Hi Bence (@underyx).

Finally, I managed to release a new version with the fixes for 2 issues. With the release your issue should go as well.
