Re: Unexpected "clean -Xd" behavior

When a directory contains nothing but an ignored subdirectory, that
subdirectory does not get removed by "git clean -Xdf".

For example, in a new directory:

# git init
Initialized empty Git repository in /tmp/foo/.git/
# echo a/ >.gitignore
# git add .gitignore
# git commit -m "Initial commit"
[master (root-commit) c3af24c] Initial commit
 1 files changed, 1 insertions(+), 0 deletions(-)
 create mode 100644 .gitignore
# mkdir -p foo/a
# touch foo/a/junk.o
# git status
# On branch master
nothing to commit (working directory clean)
# git clean -Xdn  # <--- DOES NOT MENTION foo/a

-X is to remove ignored files _only_ (DIR_SHOW_IGNORED flag). And
"foo" is not ignored according to .gitignore, so it cuts short there
and never gets to "foo/a". -x works. May be intentional, may be not
(we hit a corner case). I don't know. Commit message b991625 might

    dir.c: Omit non-excluded directories with dir->show_ignored

    This makes "git-ls-files --others --directory --ignored" behave
    as documented and consequently also fixes "git-clean -d -X".
    Previously, git-clean would remove non-excluded directories
    even when using the -X option.
