Will Norris 0a939cc19d allow more flexibility in specifying options
Options can be specified in any order (size no longer needs to be listed
first), and may be repeated.  Duplicated options overwrite previous
values.  Technically, non-size options could already be repeated... now
size can as well.  There's really not much value to this, it's just an
side-effect of allowing any order.
