From 4be636f42cd75f865204817c307eb1a7b464109c Mon Sep 17 00:00:00 2001 From: Paolo Bonzini Date: Thu, 21 Aug 2008 14:14:18 +0200 Subject: [PATCH] provide more errors for the "merge into empty head" case A squash merge into an unborn branch could be implemented by building the index from the merged-from branch, and doing a single commit, but this is not supported yet. A non-fast-forward merge into an unborn branch does not make any sense, because you cannot make a merge commit if you don't have a commit to use as the parent.
