Thanks.  Last time we discussed about this, the conclusion was that Bison 
should implement this now.  Should we rather backtrack and postpone until the 
revision is published?  I have published 3.8, but not announced it yet, so it 
probably doesn't spread too fast.  I could revert that, and publish 3.8.1 very 
soon.

I don't see why this time they would agree not to change anything.  I believe 
we already clearly stated that this is a breaking change.
