Aha... I knew it had to be something.  I couldn't quite wrap my head around the idea that sed is misbehaving.. it seems way too old and set in its ways for that.   However, I did get the -i'' syntax from somewhere.. perhaps it's a GNUism and I just forgot where I picked it up.  

Thanks for the correction!
