Ok, I read some documentation on sed and perl. Pretty confusing and
somewhat platform dependent. Thinking about it turned up the following.
Let me know if you agree:

1. We never want to inadvertently change existing linebreaks.
2. In line-mode it is impossible to change linbreaks. 
  Consequences:
  2.1 In line-mode one cannot change the number of lines in a file.
  2.2 If the user wants to change linebreaks, she has to use
byline="false".
3. A line is always finally terminated by '\n', i.e. "\r\n\n" are two
lines.
