From 8d2aa8dfac4048c964453a8983f1dc12ecdfe1c3 Mon Sep 17 00:00:00 2001 From: Jeff King Date: Wed, 30 Sep 2020 08:29:02 -0400 Subject: [PATCH] assert PARSE_OPT_NONEG in parse-options callbacks In the spirit of 517fe807d6 (assert NOARG/NONEG behavior of parse-options callbacks, 2018-11-05), let's cover some parse-options callbacks which expect to be used with PARSE_OPT_NONEG but don't explicitly assert that this is the case. These callbacks are all used correctly in the current code, but this will help document their expectations and future-proof the code. As a bonus, it also silences -Wunused-parameters (these were added since the initial sweep of 517fe807d6, and we can't yet turn on -Wunused-parameters to remind people because it has too many existing false positives).
