[PATCH 20/28] attr.c: pass struct git_attr_check down the callchain

From
Stefan Beller <sbeller@google.com>
Date
Oct 11, 2016, 00:21 UTC
Message-ID
<20161011002115.23312-21-sbeller@google.com>
In-Reply-To
<20161011002115.23312-1-sbeller@google.com>
From: Junio C Hamano <gitster@pobox.com>

The callchain that starts from git_check_attrs() down to collect_some_attrs() used to take an array of git_attr_check_elem as their parameters. Pass the enclosing git_attr_check instance instead, so that they will have access to new fields we will add to the data structure.
