[PATCH v4 00/10] nd/clone-detached

Some comment updates after discussion and squash in the fixup patch. The code is exactly the same as nd/clone-detached in pu.

Nguyễn Thái Ngọc Duy (10):
  t5601: add missing && cascade
  clone: write detached HEAD in bare repositories
  clone: factor out checkout code
  clone: factor out HEAD update code
  clone: factor out remote ref writing
  clone: delay cloning until after remote HEAD checking
  clone: --branch=<branch> always means refs/heads/<branch>
  clone: refuse to clone if --branch points to bogus ref
  clone: allow --branch to take a tag
  clone: print advice on checking out detached HEAD
