[issue10728] argparse.ArgumentParser.print_help uses sys.stdout

[Jan-Philip Gehrcke]

Jan-Philip Gehrcke added the comment:

The version action currently writes to stderr. The _VersionAction(Action)'s __call__() method finishes off with 

parser.exit(message=formatter.format_help())

and parser.exit() by default writes to stderr.

Here, Steven says "Help is definitely intended to print to stdout." and I expected the same to happen regarding the version information. Why should it go to stderr?

I see that this is a minor problem and only if someone here agrees I would open an issue for that.
