The sys.path[0] initialization change for bpo-29139 caused a regression
by revealing an inconsistency in how sys.path is initialized when executing
__main__ from a zipfile, directory, or other import location. The
interpreter now consistently avoids ever adding the import location's parent
directory to sys.path, and ensures no other sys.path entries are
inadvertently modified when inserting the import location named on the
command line.
