Branch 'C' contains the file 'c', which creates ambiguity on
case-insensitive file systems and makes the test fail:

  ++git reset --hard
  HEAD is now at ed5d5a6 B
  ++git checkout 'C^0'
  Previous HEAD position was ed5d5a6 B
  HEAD is now at 4fa59ce C
  ++git diff C B
  ++git apply --cached
  fatal: ambiguous argument 'C': both revision and filename
  Use '--' to separate paths from revisions, like this:
  'git <command> [<revision>...] -- [<file>...]'
  error: unrecognized input
  error: last command exited with $?=128
  not ok 8 - merge-recursive, when index==head but head!=HEAD
