help option should not be configurable through config files or environment variables

[SimplicityGuy]

It's a bit pointless to set -h in a config file or in an environment variable. This parameter should explicitly be banned (e.g. prevented from being read) from being set in either a config file or environment variable. Also, the help text for it should not list the environment variable name.
