From ccdc4ec3044bd108ae1e20d772f078c10df114b3 Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Mon, 21 Mar 2011 10:16:10 -0700 Subject: [PATCH] diff/status: refactor opportunistic index update When we had to refresh the index internally before running diff or status, we opportunistically updated the $GIT_INDEX_FILE so that later invocation of git can use the lstat(2) we already did in this invocation. Make them share a helper function to do so.
