-/* The value passed to this routine in current_focus_line is the index
- of the line we should have highlighted if there was no motion and if
- it matched the matcher. So, the line actually highlighted is the
- first one matching the matcher in that order: (1)
- current_focus_line after motion, (2) the first with a greater
- index, (3) the first with a lesser index.
