The builtin exception is better now, so I don't see a problem with reverting 
the original patch.

[issue32490] subprocess: duplicate filename in exception message

[Jakub Wilk]

New submission from Jakub Wilk :

Python 3.6.4 (default, Jan  3 2018, 21:10:22) 
[GCC 4.8.4] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import subprocess
>>> subprocess.call('nonexistent')
Traceback (most recent call last):
  File "", line 1, in 
  File "/usr/local/lib/python3.6/subprocess.py", line 267, in call
with Popen(*popenargs, **kwargs) as p:
  File "/usr/local/lib/python3.6/subprocess.py", line 709, in __init__
restore_signals, start_new_session)
  File "/usr/local/lib/python3.6/subprocess.py", line 1344, in _execute_child
raise child_exception_type(errno_num, err_msg, err_filename)
FileNotFoundError: [Errno 2] No such file or directory: 'nonexistent': 
'nonexistent'


Note that the name of the missing file is mentioned twice in the error message.
(Strictly speaking it's once in the message, and once in the filename 
attribute, but for a casual observer, the effect is the same.)
