dir: include DIR_KEEP_UNTRACKED_CONTENTS handling in treat_directory()

Browse Source 
Handling DIR_KEEP_UNTRACKED_CONTENTS within treat_directory() instead of
as a post-processing step in read_directory():
  * allows us to directly access and remove the relevant entries instead
    of needing to calculate which ones need to be removed
  * keeps the logic for directory handling in one location (and puts it
    closer the the logic for stripping out extra ignored entries, which
    seems logical).
