Fix deletion of range when start or end is at edge of block.

Browse source 
If the selection starts and ends in the middle of blocks, we need to merge
these after extracting the range. But we need to be careful not to merge if
the selection ends at a block, as we end up merging into a block that wasn't
selected.
