From 776670519823b5c49ff4107dc9f77706fa37bb76 Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Sun, 3 Feb 2013 13:08:18 -0800 Subject: [PATCH 1/2] combine-diff: lift 32-way limit of combined diff The "raw" format of combine-diff output is supposed to have as many colons as there are parents at the beginning, then blob modes for these parents, and then object names for these parents. We weren't however prepared to handle a more than 32-way merge and did not show the correct number of colons in such a case.
