previously we deleted the subcommand name from argv before passing to the subcommand. In this version, the deletion is done in the actual subcommands. Although this causes some duplication of code, it allows us to be more flexible about how we parse command line arguments in the subcommand, including possibly using off-the-shelf routines like getopt_long that expect the name of the command in argv[0].
