You are right. This is becuase of my inexperience with Octave. I was
experimenting on filters with even size (where to set central pixel in
those to be compatible with MATLAB?). Cutting borders myself let me use
both floor((size(SE)+1)/2) and ceil((size(SE)+1)/2).

But just using 'same' gives the same results as the version I sent
yesterday. And if someone tries it on MATLAB and it behaves differently,
perhaps we can just pad the filter with 0 properly. It's cleaner.

I attach a patch[1] using your suggestion.
