unpack-trees: add progress to clear_ce_flags()
When a large repository has many sparse-checkout patterns, the process for updating the skip-worktree bits can take long enough that a user gets confused why nothing is happening. Update the clear_ce_flags() method to write progress. Signed-off-by: Derrick Stolee <dstolee@microsoft.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
