Making the full detail explicit (based on a comment made on the pip
issue), the default PATH should match the behaviour of sys.path (so
that "pip" and "python -m pip" always execute the same thing).

So we have C:\PythonXY before %APPDATA%\PythonXY\Scripts before
C:\PythonXY\Scripts (matching stdlib before user site-packages before
system site-packages). And user site-packages is versioned because
everything else is.

The PATH setting is purely an installer change, of course - only
versioning the user scripts directory affects the core.
