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. Signed-off-by: Robert Fitzsimons <robfitz@273k.net> Signed-off-by: Junio C Hamano <junkio@cox.net>

+This test runs git-ls-tree with the following in a tree.
+
+ 1.txt - a file
+ 2.txt - a file
+ path0/a/b/c/1.txt - a file in a directory
+ path1/b/c/1.txt - a file in a directory

+ path3/1.txt - a file in a directory
+ path3/2.txt - a file in a directory
+
+Test the handling of mulitple directories which have matching file
+entries. Also test odd filename and missing entries handling.
