From 3086486d326b00ce308208e62e0e0de831f3563b Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Wed, 18 Apr 2007 12:18:25 -0700 Subject: [PATCH] Allow low-level driver to specify different behaviour during internal merge. This allows [merge "drivername"] to have a variable "recursive" that names a different low-level merge driver to be used when merging common ancestors to come up with a virtual ancestor.
