Attached PR 5322 fixes the issue.

Example to reproduce the bug:

$ touch file
$ PATH=$PATH:$PWD/file ./python -m test test_subprocess -m test_invalid_args -v
(...)
======================================================================
ERROR: test_invalid_args (test.test_subprocess.ContextManagerTests)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/home/vstinner/prog/python/master/Lib/test/test_subprocess.py", line 3050, in test_invalid_args
    stderr=subprocess.PIPE) as proc:
  File "/home/vstinner/prog/python/master/Lib/subprocess.py", line 743, in __init__
    restore_signals, start_new_session)
  File "/home/vstinner/prog/python/master/Lib/subprocess.py", line 1431, in _execute_child
    raise child_exception_type(errno_num, err_msg, err_filename)
NotADirectoryError: [Errno 20] Not a directory: 'nonexisting_i_hope'
(...)


With PR 5322 applied, the whole Python test suite pass with PATH=$PATH:$PWD/file.
