In generate_expected_cache_tree_rec(), there are currently two instances of `git ls-files` in the upstream of a pipe. In the case where the upstream git command fails, its return code will be lost. Extract the `git ls-files` into its own call so that if it ever fails, its return code is not lost. Signed-off-by: Denton Liu <liu.denton@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
