- Moved an optimization from file_compare() into f_name_cmp() (the one
  that avoids doing a string-compare on two identical char pointers),
  making it just a wrapper for f_name_cmp().  Also made file_compare()
  static because everyone now calls f_name_cmp() directly.
- Improved the flist summary that is output at high verbosity.
- Improved delete_in_dir() to better handle the push/pop semantics
  based on the depth value that is now passed in as an arg (so that
  we don't have to parse it out of the paths each time).
