Questions and answers
Which copy of a repeated line is kept?
The first one. The order of the other lines stays the same unless you choose to sort.
What does ignoring case do?
Lines such as Apple and apple are treated as the same line.
What about empty lines?
Empty lines count as lines too, so repeated blank lines are reduced to one.
