Why?  I think space-led buffers are only created with C-x C-f, it'd be
kind of pervert for a person to just create such a buffer.
Beside, the minibuffer has a buffer-undo-list, nop?  (Well, it could be
a benefit, in fact, because the M-x could be a font-lock property and be
disabled by g-f-l-m, as it was asked IIRC).
