From 363d59df1a773039d0c69ad8c3109a56bb1b491d Mon Sep 17 00:00:00 2001 From: Johannes Schindelin Date: Fri, 29 Feb 2008 01:44:56 +0000 Subject: [PATCH] path-list: add functions to work with unsorted lists Up to now, path-lists were sorted at all times. But sometimes it is much more convenient to build the list and sort it at the end, or sort it not at all. Add path_list_append() and sort_path_list() to allow that. Also, add the unsorted_path_list_has_path() function, to do a linear search.
