So using pop-to-buffer-same-window, rather than pop-to-buffer, is ok for you.

Apparently completion (or maybe read-from-minibuffer) does re-iconify a
popped up frame (that happened once in my experiments). I looked thru
the C code for read-from-minibuffer, and it has comments that talk about
preserving the frame state, but I did not see where it minimizes the
frame on return. So I don't know how to do that from elisp in
copyright-update-year.
