Yeah I was naively replicating the behavior from read_string which 
expects a character length and returns bytes read; but you are right it 
is totally the wrong semantics to use in this case. Thanks for spotting 
this. In this case is multiplying the number of bytes read as returned 
by read_string, and multiplying it by the width the right thing to 
return here?
