Patch does two things so should be two patches. I nearly split
it myself but it should be on the list a little longer anyway so
I'll leave it to you.
Other than that, looks fine to me. Ideally I'd like an Ack from
Michael or Lars, but it's simple enough that I'll take it without
if they are busy.

I have no problem with the license description change, but it should not
be in a patch doing anything else. Put it as a separate patch in the
same series.
