This allows sub-commands with unique options, without forcing cmd_multi_pack_index() to reject invalid combinations itself. This comes at the cost of some duplication and boilerplate. Luckily, the duplication is reduced to a minimum, since common options are shared among sub-commands due to a suggestion by Ævar. (Sub-commands do have to retain the common options, too, since this builtin accepts common options on either side of the sub-command). Roughly speaking, cmd_multi_pack_index() parses options (including common ones), and stops at the first non-option, which is the sub-command. It then dispatches to the appropriate sub-command, which parses the remaining options (also including common options). Unknown options are kept by the sub-commands in order to detect their presence (and complain that too many arguments were given).
