I respectfully disagree.  A line is a line.  A newline is just a marker
that tells us where one line ends and the next one begins.  What would
you think of a sort program that presented you with this output?

a   b   
c   d   
e   f   g       
e   f   
h   i   

Each of those lines ends with a tab.  In fact, what if there was one
more line that ended at the 'i' with no tab and no newline.  How should
it sort?
