selection: pay attention to hard linebreaks when search for word boundaries

Browse source 
Double-clicking on a word in the left or right margin, would line-wrap
the selection if there was a non-empty cell in the corresponding
right/left margin on the prev/next line. Regardless of whether there
was a hard linebreak or not.

Script to reprouce:

  !/bin/bash

  cols=$(tput cols)
  printf "%*coo\nbar\n" $((${cols} - 2)) f

Run, then double click either “foo” or “bar”. Neither should select
the other part.

Closes #565
