I thought about it, but didn't because I ran into the "which one do I
return, there can be multiple fields with that name" problem.

I just looked at RFC2426 in more detail, though, and it appears that
type=pref is allowed for a lot of things that can have multiple
occurences.

And if there are multiple matches, you'll always get the first, unless
one of them is pref?(), ok?
