From fad2652673247203014e2c57622a5ffe0eb5ad93 Mon Sep 17 00:00:00 2001 From: Jeff King Date: Thu, 12 May 2011 07:09:55 -0400 Subject: revert: allow reverting a root commit Although it is probably an uncommon operation, there is no reason to disallow it, as it works just fine. It is the reverse of a cherry-pick of a root commit, which is already allowed. We do have to tweak one check on whether we have a merge commit, which assumed we had at least one parent.
