[PATCH v4 1/3] builtin/commit.c: remove bespoke option callback

From: John Passaro via GitGitGadget <gitgitgadget@gmail.com>
Date: Apr 30, 2024, 14:41 UTC
Message-ID: <ce047c58aa81cc5228ae9068d790585e012491c5.1714488111.git.gitgitgadget@gmail.com>
In-Reply-To: <pull.1723.v4.git.1714488111.gitgitgadget@gmail.com>

From: John Passaro <john.a.passaro@gmail.com>

Replace git-commit's bespoke callback for --trailer with the standard OPT_PASSTHRU_ARGV macro. The bespoke callback was only adding its values to a strvec and sanity-checking that `unset` is always false; both of these are already implemented in the parse-option API.
