Where else would you call it? I don't understand much more, it seems: the original wishlist feature. The call to grow/shrink_mini_window only recomputes data about the windows for the next redisplay cycle. When that next cycle comes, it will first call pre-redisplay-function and window-size-change-functions, from prepare_menu_bars, and then, after the rest of redisplay finishes, actually perform the X repaint, by calling update_frame. So it sounds like the wish has been granted already, no? Moreover, the scenario where "prepare_menu_bars is called before auto-resizing the minibuffer window", and as result "‘window-size-change-functions’ wouldn't catch those auto-resizes", seems impossible. If that's not what is being wished, please tell more about the issue. Likewise if I'm missing something here.
