Hmm, can't this be simplified to:

    if (skip_prefix(arg, "--shallow-exclude=", &value)) {
        if (!args.deepen_not) {
            args.deepen_not = xmalloc(sizeof(*args.deepen_not));
            string_list_init(args.deepen_not, 1);
        }
        string_list_append(args.deepen_not, value);
        continue;
    }

Or, perhaps even better, declare it as plain 'struct string_list
deepen_not' in struct fetch_pack_args, rather than as a pointer, and
then in cmd_fetch_pack():

    memset(&args, 0, sizeof(args));
    args.uploadpack = "git-upload-pack";
    string_list_init(&args.deepen_not, 1);

    ...

    if (skip_prefix(arg, "--shallow-exclude=", &value)) {
        string_list_append(args.deepen_not, value);
        continue;
    }
