Actually 'pos' as implemented will remove the subfield u if it is at  
position n in the field. So we could have occurrence too. I feel like  
I'm chasing windmills a bit. Do y'all really *need* all this  
functionality in delete_subfield() :-) I guess you do or else you  
wouldn't be so interested in asking for it.

I didn't implement the -1 behavior because i wasn't quite sure how to  
do it quickly, and it seemed like too much somehow.
