I thought about that but I opted for simplicity of first picking
the exact matches.  I was unsure about the usefulness of relaxed
matching to begin with.  But I now realize that to see how useful
that would be we need to experiment it and a matrix approach
would become necessity for that.

I'd rather keep that file as is for later merge with Nico.  It
came from the delitification patch and I tried to keep the new
files as they are.
