* window.c (coordinates_in_window): Do not assume that all
one-line windows are the minibuffer, or that all minibuffers are one line high. Use MINI_WINDOW_P. * window.c (change_window_height): If the size of the window will shrink below the minimum, this code would only try to delete it if it had a parent. Well, even if the window doesn't have a parent, you want Fdelete_window to signal an error, since you're trying to resize one of the undeleteable windows into nothingness. So call Fdelete_window even if the window doesn't have a parent. * window.c (MINSIZE): Add kludge so that the minibuffer is always allowed to shrink to one line in height. (MINSIZE, CURBEG, CURSIZE): Change these so that their argument are always Lisp_Objects, not struct window *'s. (change_window_height): Changed accordingly.
