AFAICT eldoc-message-function doesn't need to be changed because it
isn't called when eldoc-mode is disabled.

The reason it ends up being called in your example is that M-:
explicitly and unconditionally enables eldoc-mode in the minibuffer.

Dmitry suggested making this behaviour conditional as a workaround, but
ultimately it would probably be best to try fixing bug#27202 without
messing with eldoc-mode in read--expression.
