That is a bit too ancient version, so I am not sure how it behaved
back then.

I am not sure if that is "working fine".  First, aren't these 'config'
files tracked?  "!/tracked_dir/*/config" or whatever you have in the
gitignore files have no effect on what is already tracked.

That is, if you replace your .gitignore with a single line,

	# ignore everything
        *

your /tracked_dir/foo/config that is already in the index (i.e. "git
ls-files tracked_dir/foo/config" would show it) would not be ignored.

So my suspicion is that (1) you do see tracked_dir/subdir1/config is
not ignored not because of any of your !tracked_dir/*/config lines
but because tracked_dir/subdir1/config is already in the index, and
(2) your tracked_dir/new_subdir/config is shown as ignored because
it is not tracked yet, and '*' tells Git that new_subdir is ignored.

By the way, this area did have a recent regression at v2.7.0, to
which a fix is percolating down to the v2.7.x maintenance track.
