From 370c873be54a6ef74f86b5e77ff722f766ebf707 Mon Sep 17 00:00:00 2001 From: Dan McGee Date: Mon, 12 Dec 2011 13:05:10 -0600 Subject: Calculate root length only once when checking for file conflicts It is quite easy to hoist this potentially repeated computation out of the loop; even if we don't end up using it, it is super cheap to do it only once.
