From: Junio C Hamano Date: Wed, 15 Aug 2007 22:46:03 GMT Subject: [PATCH] Fix read-tree merging more than 3 trees using 3-way merge Message-ID: <7vbqd8o1qs.fsf@gitster.siamese.dyndns.org> In-Reply-To: <600399.61066.qm@web52807.mail.re2.yahoo.com> For multi-base merges, we allowed read-tree -m to take more than three trees (the last two are our and their branches, and all the earlier ones, typically one but potentially more, are used as the merge base). Unfortunately, the conversion done by commit 933bf40 broke this.
