From cd1870edb6658d8118ed6015651a0ff080ae7162 Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Sun, 22 May 2005 01:31:28 -0700 Subject: [PATCH] Fix tweak in similarity estimator. There was a screwy math bug in the estimator that confused what -C1 meant and what -C9 meant, only in one of the early "cheap" check, which resulted in quite confusing behaviour.
