command lines. It was broken as a side effect of the changes to pythonw.c in b79d276041a8 for #15307. Since sys.executable no longer includes 'Python.app' in the path name, test for a framework build instead. This should give the previous behavior in nearly all cases. Whether the previous behavior is sensible is left as an issue for later releases. IDLE.app behavior was not affected as it does its own manipulation of sys.executable.
