They would also always be visible in the titlebar, the statusbar is hidden when 
the prompt is open.

Do they display those words? Arrows would take up less space and show when 
scrolling can happen, unlike those words which show when scrolling can't 
happen. A percentage would be nice, but that would take up even more space, 
especially if put in the titlebar.

Another option would be to split the arrows between titlebar and statusbar. Up 
arrow on right of titlebar, down arrow on right of statusbar. And percentage 
could be on left side of statusbar. And maybe give them their own UI color. Or 
maybe both arrows on right side of titlebar and percentage on right side of 
statusbar.

100% would be when edittop->lineno == filebot->lineno - editwinrows, but 
edittop can exceed that value when buffer is scrolled off the top of screen. 
Should percentage show >100% at that point?

Is there no case where nano beeps at top or bottom of buffer, because I thought 
it did, but testing says otherwise. A beep might be nice, but perhaps put it 
behind a toggle as it might annoy some.
