Yeah, it's intended.

Yep, a git repository metadata directory named .git_new is not special
in any way and you can use "git add" to track it if you want (for
example to add a testcase).

I think it's more that it never came up.  Excluding the current
$GIT_DIR from what "git add" can add (on top of the current rule of
excluding all instances of ".git") seems like a sensible change,
assuming it can be done without hurting the code too much. ;-)

But as you note, you are not using $GIT_DIR the way it was intended to
be used.

Thanks and hope that helps,
