[PATCH v2 08/11] rebase: remove redundant strbuf

From
PGPhillip Wood via GitGitGadget <gitgitgadget@gmail.com>
Date
Sep 13, 2021, 15:19 UTC
Message-ID
<ad3c4efc0272be8eee052a08731656a406f8f90b.1631546362.git.gitgitgadget@gmail.com>
In-Reply-To
<pull.1033.v2.git.1631546362.gitgitgadget@gmail.com>
From: Phillip Wood <phillip.wood@dunelm.org.uk>

There is already an strbuf that can be reused for creating messages. msg is not freed if there is an error and there is a logic error where we call strbuf_release(&msg) followed by strbuf_reset(&msg) and strbuf_addf(&msg).
