Subject: [PATCH 08/11] submodule.c: do not copy around submodule list
Date: Tue,  4 Sep 2018 16:01:46 -0700
Message-ID: <20180904230149.180332-9-sbeller@google.com> (raw)
In-Reply-To: <20180904230149.180332-1-sbeller@google.com>

'calculate_changed_submodule_paths' uses a local list to compute the
changed submodules, and then produces the result by copying appropriate
items into the result list.

Instead use the result list directly and prune items afterwards
using string_list_remove_empty_items.

As a side effect, we'll have access to the util pointer for longer that
contains the commits that we need to fetch.
