Nguyễn Thái Ngọc Duy (6):
  path.c: delete an extra space
  t0002: add test for enter_repo(), non-strict mode
  enter_repo: avoid duplicating logic, use is_git_directory() instead
  enter_repo: allow .git files in strict mode
  clone: allow --local from a linked checkout
  clone: better error when --reference is a linked checkout
