bugfix: highlight search patterns on the right line

scenario:
* position a wrapped line on screen
* search for the word immediately after the point of wrapping

Before this commit the word would be highlighted twice:
  - at the end of the first screen line
  - at the start of the second screen line

Now it shows up at the right place.
