But we still have work to do for cursor up/down.

some more logging

Still lots of signs it's all messed up, but I can't be sure until I
bring all the other keyboard shortcuts in sync.
I just need a better data structure that simplifies the logic. Perhaps
talk in terms of screen lines. In which case:
We'll need to convert lines to screen lines at some point.
We'll need to fix up screen lines when inserting and deleting
characters.

I've been only thinking about up arrow when cursor is at top of screen.
Hopefully this is better.

I'd wrapped currx in two conditionals, and not noticed that it gets
reclaimed within the other.
The hint is clearly more work than it's worth. Just take it out.

As usual, binary search is hard to get right. This time I was never
actually selecting between left and right when they were just one
character apart.

bugfix: ensure Cursor_line is always on a text line
...
Manual test used here:
abc
```lines
{"p1":{"y":72,"x":82},"mode":"line","p2":{"y":29,"x":169}}
```
def
```lines
{"p1":{"y":36,"x":56},"mode":"line","p2":{"y":59,"x":163}}
```
```lines
```
ghi
jkl
Hitting page-down moves the cursor from abc to ghi. The 'ghi' line
should be fully visible on screen.

Still some limitations. The text cursor has to be visible on screen, so
if you have a long series of drawings without intervening lines of text
you won't be able to scroll through them all.
