I took a more precise approach with outline--cycle-state, where the +1 
case is only handled when the subtree end is point-max, otherwise the 
overlay-end must equal end of subtree point in all other cases.

I rewrote outline-cycle-buffer; it now first checks that the buffer has 
top-level headings before attempting to show only top-level headings, 
thus avoiding the disconcerting state where all buffer content is 
reduced to "...". If buffer has no outline headings, we still get an 
annoying message toggle from "All headings" to "Show all".

Also this avoids using pcase, which is awful.
