I agree; replacing (2x, i4) with i6 works.  It's all down to x-editing 
problems.  I must stop now but will resume in the morrow.

I believe both problems (and the one I patched) are down to the logic 
determining the present pointer, the maximum but unprinted pointer and 
the pending spaces.  I just do not see it yet.
