As I said earlier in the thread, the __package__ module global
distinguishes the two cases:

~$ mkdir pkg
~$ touch pkg/__init__.py
~$ vim pkg/__main__.py
~$ cat pkg/__main__.py
import sys
if __package__ is None:
    cmdline = [sys.executable] + sys.argv
else:
    cmdline = [sys.executable, '-m', __package__] + sys.argv[1:]
print(cmdline)
~$ python pkg/__main__.py arg1 arg2
['q:\\tools\\Python27\\python.exe', 'pkg/__main__.py', 'arg1', 'arg2']
~$ python -m pkg arg1 arg2
['q:\\tools\\Python27\\python.exe', '-m', 'pkg', 'arg1', 'arg2']
