consider splitting whitespace per line

[carocad]

I received some feedback that it would be better if parcera would split the whitespace per line so that instead of having single whitespace catching all newlines, it would be split per line. I am still not sure exactly what the use case behind it is nor why it "should" be in parcera and not as a helper function in the consumer side. However, in order to remember it, I will document it here and think about it a bit more.
