Looking more closely, I also see that the above change is already
released in 1.8.2 versions. Given that, I don't think it makes sense to
to still try to provide this capability to get backward compatible
behaviour, since this would cause a off-by-one error the other way when
talking to 1.8.2.x servers...
However, since I pretty much finished the code for this, I'll send over
the patches and let you decide wether to include them or not. If you
want to include them but they need to be changed in some way, just let
The first patch of the series should be merged regardless.
