[PATCH 2/3] dir_struct: add collect_ignored option

From: Jeff King <hidden>
Date: 2016-06-15 22:43:15
Subsystem: the rest · Maintainer: Linus Torvalds

When set, this option will cause read_directory to keep
track of which entries were ignored. While this shouldn't
effect functionality in most cases, it can make warning
messages to the user much more useful.
