If I use rectilinear as an infill, there are holes in the beginning and end of the fill. not good.
I have not noticed this before and I assume it was because I had the extrusion multiplier set at 1. I reduced it to 0.96 to solve a messy first layer and get proper dimensions.
But now the print is exactly like the picture. I can count 10 holes either side of the beginning void also. I am not sure that increasing the overlap will fix that.
Apparently there are things in a model that seem to divert slic3r's attention. I was getting the cannot close holes with xx points messages. I redid some parts of the model one by one and eventually found the things that were giving me the can't close errors and when I looked at this issue again it seemed to be resolved. I haven't tried a real print yet, but the picture appears to close these holes now.
