Here's a patch series to do that. The first three are just preparatory
cleanups; the last one is the interesting bit.

  [1/4]: t5600: fix outdated comment about unborn HEAD
  [2/4]: t5600: modernize style
  [3/4]: clone: factor out dir_exists() helper
  [4/4]: clone: do not clean up directories we didn't create
