Subject:    [PATCH v4 26/33] submodule--helper: libify determine_submodule_update_strategy()
From:       Ævar Arnfjörð Bjarmason  <avarab () gmail ! com>
Date:       2022-08-31 23:18:08
Message-ID: patch-v4-26.33-512106bc6be-20220831T230519Z-avarab () gmail ! com
[Download RAW message or body]

Libify the determine_submodule_update_strategy() by having it invoke
die_message() rather than die(), and returning the code die_message()
returns on failure.
