The python launcher does not parse the shebang if arguments for the Python interpreter are given on the command line.  For example:

py.exe # uses shebang line
py.exe -u # does NOT use shebang line

The attached patch fixes this.

I do test the launcher in a standalone environment, but it's not straightforward to test in a standard build or buildbot environment. For example, it needs 4 sets of Python (Python 2.x and 3.x, 32-bit and 64-bit builds for each) setup in the Windows registry.

The test script I use is at
