To reproduce, run:

src/nano --ignore --smooth +1 NEWS

Then press and hold PageDown. See how the cursor is visible both at the top of the wdit window and on the status bar. When you've reached the end of the file, press and hold PageUp. Same thing: flickering cursor It occurs also when holding <Down> for a long time, but it is much less frequent and less distracting, but still not right.

Bug exists only in git -- 2.8.5 and before are not affected.

The offending commit is 7d46eff7 (always redrawing the help lines). The fixing of bug #51356 caused this.

So... we should /not/ always redraw the help lines, but only when needed. So... when it's needed, set 'currmenu' to something other than MMAIN, so the main loop will redraw the lines, like it was before.
