pip.bat doesn't install to venv

[mirober]

Normal behaviour of virtualenv is to create new versions of a lot of the Python code in Scripts/ (https://www.python.org/dev/peps/pep-0405/#creating-virtual-environments), including the executable.

the code in cpython that looks for venvs is this:

    executable = sys.executable
    exe_dir, _ = os.path.split(os.path.abspath(executable))
    site_prefix = os.path.dirname(exe_dir)
    sys._home = None
    conf_basename = 'pyvenv.cfg'
    candidate_confs = [
        conffile for conffile in (
            os.path.join(exe_dir, conf_basename),
            os.path.join(site_prefix, conf_basename)
            )
        if os.path.isfile(conffile)
        ]

I tried doing the same thing using pip.bat as a template and it couldn't find it - pip.bat calls .python/python.exe, which resolves to Program files/talon/python.exe, then python looks for the pyvenv.cfg in Program Files/talon and Program Files and doesn't find it

Ok, my idea is kind of dirty, but I think I can fix this:

1. use the start flag to NOT import site -S
2. set sys.executable in my pip.bat shim to the venv
3. import site

Should be fixed in latest beta.
