There is quite a bit of Python's lexical analysis that is specified in places 
other than the formal notation. That does not mean it is undefined. It is well 
defined in the lexer code and the documentation. You suggest that a "rule 
probably should be added to the lexer to make this explicit." That is not 
necessary. The rule is already there.
