From b81f925f709a10b37fb4fcd03629b55bc890a478 Mon Sep 17 00:00:00 2001 From: Jonathan Nieder Date: Tue, 17 Aug 2010 01:52:48 -0500 Subject: [PATCH] merge: do not mistake (ancestor of) tag for branch If no branch 'foo' exists but a tag 'foo' does, then git merge foo^ results in Merge branch 'foo' (early part) as a commit message, because the relevant code path checks that refs/heads/foo is a valid refname for writing rather than for reading.
