[PATCH v4 0/3] relative path regression fix

Remove implementations on UNC names in patch v3. So patch v4 is the same like v2, but with minor update for commit logs.

Jiang Xin (3):
  test: use unambigous leading path (/foo) for mingw
  relative_path should honor dos-driver-prefix
  Use simpler relative_path when set_git_dir
