 So enforce that in code then, clear the SPECIAL flag where appropriate 
and do not try to handle it in one place while leaving other ones to 
behave randomly (i.e. a supposedly fixed field width varies depending on 
the two uppermost digits).  Please note that it's only your proposed 
change that introduces that randomness, right now code does what's 
supposed and documented to, except a bit inconsistently.

 I pointed out an inconsistency with the intent to propose a fix once a 
consensus have been reached, one way or another.  And I think shifting the 
inconsistency to a different place, which is what your proposal does, 
isn't really a complete solution, although I do recognise the improvement.
