[PATCH 1/8] dir.c: git-status --ignored: don't drop ignored directories

[Karsten Blees <karsten.blees@gmail.com>]

'git-status --ignored' drops ignored directories if they contain untracked
files in an untracked sub directory.

Fix it by getting exact (recursive) excluded status in treat_directory.
