[PATCH v4 0/8] Fix GIT_CEILING_DIRECTORIES that contain symlinks

v4 of the series; see the cover letter for v3 [1] for more editorial comments.

Changes since v3:

* For "test-path-utils longest_ancestor_length", normalize all of the
  paths using normalize_path_copy() to counteract the path mangling
  carried out by bash on Windows.  (Thanks to Johannes Sixt for his
  helpful advice.)

* Rebased onto a more recent master.
