How do they make things better, and what things, exactly? My recollection is that this was about consistency, not correctness. Also, the original discussion was about quite a few separate changes, some of which were installed, so I don't think I have a clear idea which parts you allude to. > Would it be possible to add the new calculations with a defcustom to > say whether to use the new or old methods? I don't think defcustom is the proper way of handling differences in behavior at this low level.
