They shouldn't overlap.  The most efficient would be if the scrollbar
were a separate subwindow, one column wide and editwinrows high.

Eh... I need to tell you what to do, but later you still want credit?
Just pick the correct solution: one that doesn't do silly things.

In the past year I have optimized the clearing/drawing of each line,
using wclrtoeol() instead of writing a series of blank characters.
Making this any less efficient is not desirable.
