[issue13533] Would like Py_Initialize to play friendly with host app

[Yukihiro Nakadaira]

Yukihiro Nakadaira added the comment:

This problem easily happen when there is no python installation and there is 
standalone python application compiled with py2exe or cx_Freeze (e.g. 
Mercurial).  Such application have pythonXX.dll in its directory.  But its 
python library can not be loaded normally.  So an application, which loads 
pythonXX.dll to check if python is available and uses it if possible, is 
terminated when loading python.

Vim uses python as embedding scripting language.  Vim loads pythonXX.dll when 
:python command is used.  And this problem is reported occasionally.

[issue20763] old sys.path_hooks importer does not work with Python 3.4.0rc1

[Yukihiro Nakadaira]

New submission from Yukihiro Nakadaira:

Steps to reproduce:

$ cat a.py
import sys

class MyFinder:
def __init__(self, path):
if path != __myfinder__:
raise ImportError()

def find_module(self, fullname, path=None):
return None

sys.path_hooks.append(MyFinder)
sys.path.insert(0, '__myfinder__')

import time
print('OK')

$ python3.3 -V
Python 3.3.2+

$ python3.3 a.py
OK

$ python3.4 -V
Python 3.4.0rc1

$ python3.4 a.py
Traceback (most recent call last):
  File a.py, line 14, in module
import time
ImportError: spec missing loader


On Ubuntu 13.10.
python3.3 is ubuntu's package.
python3.4.0rc1 is built by myself.

Vim's custom importer does not work for it.

[issue7472] email.encoders.encode_7or8bit(): typo iso-2202. iso-2022 is correct.

 In other words, I think the correct thing to do is to delete that if test.

I think so too.

 Do you have a case where the code produces incorrect behavior that your patch 
 turns into correct behavior?

No, I don't.  I just found a typo.

The code for iso-2022 was added by issue #804885.  But I don't know why it 
was requested.
