Re: [PATCH v2 08/11] commit-graph: stop using optname()

> Stop using optname() in builtin/commit-graph.c to emit an error with
> the --max-new-filters option. This changes code added in 809e0327f57
> (builtin/commit-graph.c: introduce '--max-new-filters=<n>',
> 2020-09-18).

> See 9440b831ad5 (parse-options: replace opterror() with optname(),
> 2018-11-10) for why using optname() like this is considered bad,
> i.e. it's assembling human-readable output piecemeal, and the "option
> `X'" at the start can't be translated.

> It didn't matter in this case, but this code was also buggy in its use
