That crossed my mind too. So I had started looking for its existing
implementation, and found this in buff-menu.el inside list-buffers--refresh
function:

    (string= (substring name 0 1) " ")

I was wondering if that should be wrapped into a function like
buffer-internal-p (based on the many docstrings like below in buff-menu.el:
"By default, the Buffer Menu lists all buffers except those whose names
start with a space (which are for internal use)."). Having a function like
this would be better than having that logic implemented in different ways
in the emacs core.

I just don't know the best place to put this function definition. Eli?
