Yup. I also see this in the "(emacs) Undo" Info node:

   Some specialized buffers do not make undo records.  Buffers whose
names start with spaces never do; these buffers are used internally by
Emacs to hold text that users don’t normally look at or edit.

But I cannot find the code that implements that.

It would be nice to have these places to use the same defsubst.

Btw I confirm the fix. Thanks!
