From 54e1abce90ed44d0674772a735ac387ce3e264f2 Mon Sep 17 00:00:00 2001 From: Carl Worth Date: Wed, 3 Oct 2007 00:03:53 -0700 Subject: Add test case for ls-files --with-tree This tests basic functionality and also exercises a bug noticed by Keith Packard, (prune_cache followed by add_index_entry can trigger an attempt to realloc a pointer into the middle of an allocated buffer).
