I don't like this, because IIUC, this is only needed because of the:

(find-file-noselect (diary-check-diary-file) t)

in diary-mark-entries.

It should be implicit that find-file-noselect does not mess with the
window layout, and we should not need to wrap every call to it in save-*
constructs to guard against inappropriate find-file-hooks.

I've made some changes to diary-lib.el that mean there is no longer an
error in the initial example; however the calendar buffer ends up being
replaced with the diary buffer.

I didn't read in detail all that you want to do, but I think the only
way you can do it at present is by advising find-file rather than using
find-file-hook.
