[PATCH 0/3] Clean up some memory leaks in and around dir.c

Some memory leaks in dir.c were making it hard for me to find my own leaks
in merge-ort. I followed a few threads and tried to both clean up the leaks
and make the API less prone to incorrect use.

Elijah Newren (3):
  dir: fix leak of parent_hashmap and recursive_hashmap
  dir: make clear_directory() free all relevant memory
  dir: fix problematic API to avoid memory leaks
