I would prefer that the case of ~X matches the case of the hex characters, but 
can't specify more than R5RS here.  Note that the reference implementation 
maes use of NUMBER->STRING.

I consider it useful to detect this as an error, but there are other sensible 
ideas.  E.g. one possible return value for FORMAT is the list of unused 

I prefer that FORMAT invoke ERROR rather than failing and returning #F, as 
SLIB specifies.

However, I prefer to leave FORMAT's return value unspecified in srfi-48 and 
come to concensus on an advanced format srfi.
