Hi Stefan,
This is mostly fine where it is making sure things are consistent.
However, in some cases they were consistent and said gpl v2+.
We are on dubious legal grounds no stating that wasn't the intent
and would need to check closely for any potential additional copyright
holders etc.
So, I'd much rather we just fixed the ones that were clearly
inconsistent and left the ones that were stated as gpl v2+
alone.
Sorry to be fussy about this, but it's a legal mine field
we are definitely best to avoid.
Jonathan

I would leave this alone.

This is one of the ones that is ambiguous ones that I suggested
we clean up. As it was marked with two disagreeing statements,
I would think we are probably fine saying it wasn't clear and
clarifying the license.
