(on an overflow)
when you arrow-key down the viewport
you cannot "access" the last entry shown
as in, cursor focus will always be viewport height (depth) -1
you can /see/ the last entry,
but you have to click down to "access" it
(& so once again you can /see/ the next entry, but cannot "access" it)
- oh, so this also why if (on overflow) you END [key], you (now)
see 2 whitespaces (vs. prior, only 1)
- similarly, say you are 1 line before end of viewport
(end of results list, such that 1 result is yet to come into focus)
& you rename a pair of files in the middle of viewport
on rename, viewport "jumps", & at that point
- while /selection/ has not changed
the viewport "jumped", now showing 1 whitespace
