From 8082d8d3050e3fdd7b0f13c7a7b3ad68af7f478a Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Wed, 21 Sep 2005 00:18:27 -0700 Subject: Diff: -l to limit rename/copy detection. When many paths are modified, rename detection takes a lot of time. The new option -l can be used to disable rename detection when more than paths are possibly created as renames.
