5754 automatically wraps when the frame is too narrow to contain it,
5755 and that causes any calculations made here to come out wrong. The
5756 end is some nasty buggy behavior, including the potential loss
5759 Disabling this code is either not sufficient to fix the problems
5760 completely, or it causes fresh problems, but at least it removes
5761 the most problematic symptom of the minibuffer becoming unusable.
5763 -----------------------------------------------------------------
5765 Now, strictly speaking, we can't be sure that this is accurate,
5766 but the window manager will get around to dealing with the size
5767 change request eventually, and we'll hear how it went when the
5768 ConfigureNotify event gets here.
5770 We could just not bother storing any of this information here,
5771 and let the ConfigureNotify event set everything up, but that
5772 might be kind of confusing to the Lisp code, since size changes
5773 wouldn't be reported in the frame parameters until some random
5774 point in the future when the ConfigureNotify event arrives.
5776 We pass 1 for DELAY since we can't run Lisp code inside of
