Unfortunately, source packages are also affected. That means that if 
iepngfix upstream don't agree to relicense this particular version,
we will have to repackage .orig.tar.gz anyway. But in the latter case
I think I prefer to strip this file completely, as it serve very little 
purpose and, if I understand correctly, doesn't even work out of the 
box.

While I detest embedded code copies, it seems that I cannot make 
docutils use other s5 files, as they were purposely modified by 
docutils upstream.

They don't. In fact, they don't mention this file at all (which is a bug 
on its own). But let's refrain from mass bug cloning until we have 
iepngfix upstream opinion.
