Reading the series backwards from the end, I would expect that the
above to replicate the current behaviour to allow commands to have
both "command wide" options and "per subcommand" options, e.g.
$ git notes get-ref --ref=amlog
error: unknown option `ref=amlog`
usage: git notes get-ref
$ git notes --ref=amlog get-ref
refs/notes/amlog
Assuming that is how the new OPT_SUBCOMMAND() interacts with the
dashed options in a single "struct option []", everything I saw
so far in [10-20/20] makes sense. [17/20] has another instance
of the above, dashed-options and subcommands mixed in an array,
to parse the option for "git remote --verbose <subcmd>" that applies
to all subcommands.
Thanks.
