My attempt:

>>> sub = re.compile(r"\s*?(\n|$)").sub
>>> sub("<EOL>", "alpha   \nbeta   \r\n\ngamma\n")
'alpha<EOL>beta<EOL><EOL>gamma<EOL>'
>>> sub("<EOL>", "alpha   \nbeta   \r\n\ngamma")
'alpha<EOL>beta<EOL><EOL>gamma<EOL>'
>>> sub("<EOL>", "alpha   \nbeta   \r\n\ngamma\t")
'alpha<EOL>beta<EOL><EOL>gamma<EOL>'
