From cefd43b7f9b86b1c5de5216a8a03fac5e611afa9 Mon Sep 17 00:00:00 2001 From: Federico Cuello Date: Thu, 21 Oct 2010 19:12:02 -0300 Subject: [PATCH 1/2] Fix git-apply with -p greater than 1 Fix the case when the patch is a rename or mode-change only and -p is used with a value greater than one. The git_header_name function did not remove more than one path component.
