Yes, so it seems. The per-directory ignore-files don't work.
"--exclude-from=" (aka -X) still does.

No, I honestly believed that Git-known files can be ignored. According
to Linus I must be wrong, but I have an excuse:

    $ mkdir aaa
    $ cd aaa
    $ git init
    Initialized empty Git repository in .git/
    $ uname >abc
    $ git add .
    $ ls > .gitignore
    $ git ls-files -X .gitignore
    $ git ls-files -X .gitignore -i
    abc
