highlighting the block should not reverse video the checkerboard

[drj11]

the block is highlighted in reverse video. If the block includes the last line of the file and the checkerboard zone beyond the end of the file is visible, then the checkboard is also shown in reverse video.

This may be hard to see on some displays because the checkerboard is usually 50% "on". But i guess that on my mac the subpixel rendering and/or the reverse video isn't gamma corrected properly, so i can see it as a change in brightness even if i can't see the individual pixels change.

To show:

• start tine on empty file: tine newfile
• type in "Hello" or somesuch
• Ctrl-K Ctrl-K to make a single line block
