New submission from Christian Heimes:
While I was testing #16499 I found a small bug in the venv code of the site
module. The code in site.venv() doesn't use abspath() to sanitize the path to
executable_dir. This leads to wrong behavior when a venv is created in the root
of a hg checkout and the non-venv interpreter is called with a relative path:
(venv) heimes@hamiller:~/dev/python/cpython/venv$ ../python -c "import sys;
print(sys.path)"
['', '/usr/local/lib/python34.zip', '/home/heimes/dev/python/cpython/Lib',
'/home/heimes/dev/python/cpython/Lib/plat-linux',
'/home/heimes/dev/python/cpython/build/lib.linux-x86_64-3.4-pydebug',
'/home/heimes/dev/python/cpython/venv/lib/python3.4/site-packages']
The fix is simple, straight forward and totally harmless:

+++ b/Lib/site.py
