I also agree with this.  I think this was how I originally tried to
solve this problem (it was a while ago) but it didn't seem supported.

I could update `revert-buffer' to include the logic for IGNORE-AUTO and
NOCONFIRM that are used in `revert-buffer--default' with some additional
logic to handle buffers without associated files.

Should I leave this logic in `revert-buffer--default' as well or have it
only exist in `revert-buffer'?

I believe that would also require changing `help-mode' to use
`revert-buffer-function' and `revert-buffer' instead of binding
`help-mode-revert-buffer', right?
