   8This test registers the following filesystem structure in the cache:
   9
  10    path0/file0 - a file in a directory
  11    path1/file1 - a file in a directory
  12
  13and attempts to check it out when the work tree has:
  14
  15    path0/file0 - a file in a directory
  16    path1       - a symlink pointing at "path0"
  17
  18Checkout cache should fail to extract path1/file1 because the leading
  19path path1 is occupied by a non-directory.  With "-f" it should remove
  20the symlink path1 and create directory path1 and file path1/file1.
