The startup refactoring means command line settings are now applied after settings are read from the environment. This updates the way command line settings are applied to account for that, ensures more settings are first read from the environment in _PyInitializeCore, and adds a simple test case covering the flags that are easy to check.

@zooba Could you have a look over this and see if any of the newer Windows settings are affected? I don't think they are, since they're envvar only, and this was a problem with envvar vs cmdline settings, but it doesn't hurt to double check. |
