[docs] [issue20598] argparse docs: '7'.split() is confusing magic

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

Using str.split() for splitting full command line on arguments is anti-idiom. More correct way is to use shlex. But this is overkill for argparse examples (and in most cases we already have a list sys.argv). Explicit lists look clear enough.

The patch LGTM.
