That's true, I guess it's better to be safe than sorry.

You're right, it's unnecessary; thanks for noticing.  (I had first tried
to fix it without that macro and on testing it changed the selected
window from the minibuffer to the todo-mode buffer, so that's why I
thought I needed with-selected-window, but I must have used different
functions, I can't remember anymore.)

I installed both patches in separate commits to keep the author credits
clear (with a slightly tweaked error message in your patch) and am
closing this bug.  Thanks again.
