When pip installs a package into site_packages, does it at any point run
package-specific installation code? setup.py? More specifically, can
pip install an IDLE extension. If so, I think installing pipgui should
add 'x_pipgui.py' to idlelib, if it exists, and add a section to
idlelib/config-extension.def. Using the existing extension mechanism
would be an alternative to patching IDLE to conditionally add pipgui to
