From ab1630a3ed31d6ec5ae83769c78ed542fe3c4a28 Mon Sep 17 00:00:00 2001 From: "robfitz@273k.net" Date: Fri, 7 Oct 2005 16:54:06 -0700 Subject: [PATCH] Fix wrong filename listing bug in git-ls-tree. This patch fixes a bug in git-ls-tree in which the wrong filenames are listed if the exact same file and directory contents are present in another location in the tree. Added a new series of test cases for directory and filename handling.
