[PATCH 3/6] fetch-pack: refactor add_haves()

From
JTJonathan Tan <jonathantanmy@google.com>
Date
Apr 9, 2021, 01:10 UTC
Message-ID
<b07e52ec18f46fb85d49ba0e1e6e8ad22845af9e.1617929278.git.jonathantanmy@google.com>
In-Reply-To
<cover.1617929278.git.jonathantanmy@google.com>

A subsequent commit will need part, but not all, of the functionality in add_haves(), so move some of its functionality to its sole caller send_fetch_request().
