From what I can tell, if you create a path hook in sitecustomize.py,
argv will have been set before the hook is called for the script.
So, for example:
import sys
edit_done = False
def argv_setter_hook(path):
global edit_done
if edit_done:
return
try:
argv = sys.argv
except AttributeError:
pass
else:
argv[:] = get_unicode_argv()
edit_done = True
raise ImportError # let the real import machinery do its work
sys.path_hooks[:0] = [argv_setter_hook]
