I actually have been applying the various patches in the one I build
privately. It shouldn't be too hard to just commit them and have them
available in github. I would rather not fork though as that would make
one of us the decision makers for stuff that sometimes is not really
easy to decide on (As an example, I just saw the discussion related to
the ABI change for the nonset variable vs empty string). Instead I
would gladly give a helping hand to Lars even though I am new around
here.
