If consistency with Smulx is desirable then I think it is. Otherwise
when we populate the escape sequence for the underline we'll need to map
from the face underline style to the sequence underline style.
Reordering like this makes them match so we don't have to do any extra
processing later, but if preferable I can retain the original order and
add a helper function to map to the sequence value.
