[PATCH v3 6/7] fetch-pack: move common check and marking together

From
JTJonathan Tan <jonathantanmy@google.com>
Date
Jun 14, 2018, 22:54 UTC
Message-ID
<97f9a133e409f0fa898132a6f972e564db522dbf.1529016350.git.jonathantanmy@google.com>
In-Reply-To
<cover.1529016350.git.jonathantanmy@google.com>

When receiving 'ACK <object-id> continue' for a common commit, check if the commit was already known to be common and mark it as such if not up front. This should make future refactoring of how the information about common commits is stored more straightforward.

No visible change intended.
