[docs] [issue20970] contradictory documentation for prog option of argparse

New submission from Aaron Meurer:

I hope it's OK to report documentation issues on this tracker.  Reading http://docs.python.org/3.4/library/argparse.html#prog I had to do a double take. The documentation states, "By default, ArgumentParser objects uses sys.argv[0] to determine how to display the name of the program in help messages." The example then goes on to show it *not* using sys.argv[0] (sys.argv[0] in the second example would be 'subdir\myprogram.py'). 

Furthermore, even though the commands are apparently POSIX style, with a $ prompt and using cd, they use a backslash to access a subdirectory.
