[PATCH v2 0/9] Fix GIT_CEILING_DIRECTORIES that contain symlinks

v2 of the series, with the following changes from v1:

Patch 2/9 is new.

Patch 4/9: remove an unnecessary memcpy(). (This change doesn't affect the tip of the branch because the memcpy() was removed anyway in the second-to-last patch.)

Patch 8/9: remove a superfluous "len++", and improve the excuses in the commit message for removing the tests of longest_ancestor_length().

Thanks to Junio for his helpful comments.

Michael Haggerty (9):
  Introduce new static function real_path_internal()
  real_path_internal(): add comment explaining use of cwd
  Introduce new function real_path_if_valid()
  longest_ancestor_length(): use string_list_split()
  longest_ancestor_length(): explicitly filter list before loop
  longest_ancestor_length(): always add a slash to the end of prefixes
  longest_ancestor_length(): use string_list_longest_prefix()
  longest_ancestor_length(): resolve symlinks before comparing paths
  t1504: stop resolving symlinks in GIT_CEILING_DIRECTORIES
