readline() always includes the '\n' that terminates the line, so any 
'blank' line that is read will be returned as a simply '\n'.  The only 
time readline() won't return a line terminated with '\n' is if the last 
line of the file isn't terminated with '\n' (common on Windows), in which 
context a blank line is meaningless.
