[PATCH 0/3] merge-recursive: replace string_list with hashmap

Code was using two string_lists, one for the directories and one for the files. The code never checks the lists independently so we should be able to only use one list. The string_list also is a O(log n) for lookup and insertion. Switching this to use a hashmap will give O(1) which will save some time when there are millions of paths that will be checked.

Also cleaned up a memory leak and method where the return was not being used.

Kevin Willford (3):
  merge-recursive: fix memory leak
  merge-recursive: remove return value from get_files_dirs
  merge-recursive: change current file dir string_lists to hashmap
