Thanks, another question: if I restore the original value of
phys_cursor->x after the call to display_and_set_cursor,
erase_phys_cursor gets very confused the next time it is called.

If I don't restore the original value, everything appears to work fine.

Should I replicate the cursor offset logic in erase_phys_cursor, or
should I keep the new value of phys_cursor->x?  Thanks.
