New issue 1296: Python setuputils fail to record __hg_version__.py* files as installed
https://bitbucket.org/yt_analysis/yt/issues/1296/python-setuputils-fail-to-record

yurivict:

setup.py writes these files separately, and it looks like this causes the problem.

The install command
```
python setup.py install --record {file-list}
```
fails to record these files.
