JMarc,
Thank you for your guidance. Attached is an updated patch and below I respond
to your comments.

That works.

I wouldn't mind trying to address this if you think that would be better. For
now I don't allow for this situation by disabling the function in getStatus. I
didn't realize that it's possible to have a hidden window without a visible
window. The current patch disables the function in this situation. I don't know
how to check for the existence of a hidden buffer without a visible buffer.

Done.

I put in some checks.

Done.

Done.

If there are more windows open, buffer-forall iterates over the buffers in the
current window, treating a buffer as hidden as designated in the current
window. When a new window is opened it treats all of the open buffers as
hidden. The default of buffer-forall of not iterating over hidden buffers is
thus nice in the case that a user doesn't know what a hidden buffer is or
doesn't know that the buffers in the other windows would be affected by
buffer-forall because they are automatically available as hidden.

Done.
