Description
allow_unregistered should be an option for the parse_environment parser.
Given a suite of tools that share some but not all options, parse_environment forces all programs to register all possible options.
Given a suite of tools progb and progc such that:
progb --opta --optb progc --opta --optc
are valid options to parse, using parse_environment(desc, "PREFIX_") will only work for PREFIX_OPTA. If PREFIX_OPTB or PREFIX_OPTC are set the other program will fail.
