Confirmed, the issue here is a little more complated than the other PR, the problem is fold converts ('0' 
<= c && c <= '9') into "(c - '0') <= 9u"  but it converts the types to unsigned int as it wants to do an 
unsigned comparision.  The other issue since the subtracts is done in two different types it is not 
recognized by either DOM or PRE.
