With HTTP, for example, lines are terminated with \r\n.  The lines 
themselves (in the header, at least) have constraints on the character 
range they allow, so one might want to error on solo \n but break on a 
\r\n, etc.  Still, I don't know why anyone would use readln() for 
processing a network protocol, so perhaps the issue is moot.
