dir: add a usage note to exclude_per_dir

As evidenced by the fix a couple commits ago, places in the code using exclude_per_dir are likely buggy and should be adapted to call setup_standard_excludes() instead. Unfortunately, the usage of exclude_per_dir has been hardcoded into the arguments ls-files accepts, so we cannot actually remove it. Add a note that it is deprecated and no other callers should use it directly. Signed-off-by: Elijah Newren <newren@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
