From 4a92d1bfb784b09641180d164e7d719080165dc4 Mon Sep 17 00:00:00 2001 From: Alex Riesen Date: Sat, 27 Sep 2008 00:56:46 +0200 Subject: [PATCH] Add remove_path: a function to remove as much as possible of a path The function has two potential users which both managed to get wrong their implementations (the one in builtin-rm.c one has a memleak, and builtin-merge-recursive.c scribles over its const argument).
