From d6cece51b83db5d8a523c4ba857013c4242e310e Mon Sep 17 00:00:00 2001 From: Jeff King Date: Thu, 20 Oct 2016 02:20:07 -0400 Subject: [PATCH] diff_aligned_abbrev: use "struct oid" Since we're modifying this function anyway, it's a good time to update it to the more modern "struct oid". We can also drop some of the magic numbers in favor of GIT_SHA1_HEXSZ, along with some descriptive comments.
