Subject: [PATCH v7 01/28] refs: ref_iterator_peel returns boolean, rather than peel_status

From: "Han-Wen Nienhuys via GitGitGadget" <[email-masked]>
Date: Mon, 19 Apr 2021 11:37:29 +0000

From: Han-Wen Nienhuys <[email-masked]>

Before, the cached ref_iterator would return peel_object() output directly. This
led to spurious differences in the GIT_TRACE_REFS output, depending on the ref
storage backend active.
