print_usage_error:
test-config parses its arguments in an if-else chain, with one arm for each available subcommand. Every arm expects (and checks) that argv corresponds to something like "config <subcommand> [<subcommand args>]". This means that whenever we want to change the syntax to accommodate a new argument before <subcommand> (as we will do in the next patch), we also need to increment the indexes accessing argv everywhere in the if-else chain. This makes patches adding new options much noisier than they need to be, besides being error-prone. So let's skip the "config" argument in argv and argc to take the extra complexity out of such patches (as the following one).
