From 23a64c9e771e3caf19cf2ee9a32c8942ddde4a81 Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Fri, 15 Jan 2010 22:37:32 -0800 Subject: conflict-marker-size: new attribute This can be specified to set the length of the conflict marker (usually 7) to a non-default value per path. Only the callers of ll_merge() that are aware of the per-path attributes are modified.
