Good point :)

Nonetheless, io.lines does have a concept of lines, it's just that it's stripping the EOL marker by default, which is not necessarily what one might  want when computing a hash or something.

In 5.2, you might want to use the '*L' option, instead of the default '*l' one:

	• "*l": reads the next line skipping the end of line, returning nil on end of file. This is the default format.
	• "*L": reads the next line keeping the end of line (if present), returning nil on end of file.
