From 327f18c3b28225dcfcaa0409b880136f7e1d1bf6 Mon Sep 17 00:00:00 2001 From: zeripath Date: Thu, 22 Oct 2020 00:08:44 +0100 Subject: [PATCH] Fix initial commit page & binary munching problem (#13249) * Fix initial commit page Unfortunately as a result of properly fixing ParsePatch the hack that used git show to get the diff for this failed. This PR fixes this using the "super-secret" empty tree ref to make the diff against.
