I just wanted to note that this patch redefines the usual meaning of '?' 
wildcard, which means "exactly one or zero characters" - and that is the 
way it's working now. I'm not sure if this change is good, it is 
certainly surprising...

What the original poster wanted is commonly known as '.' wildcard, which 
means "exactly one character".
