Hm. Yes, I can see now I misunderstood the [:space:] character class. It 
was not exactly what I thought. I believed \r and \n belonged to this 
character class (though I understand it can not).

This explains why the pattern did not match. However it does not explain 
why it matched later in point 3. I am still so surprised by this that I 
had to test it once again to be sure.
