I think let % to be default for dummy indices. This is not a problem at all.
We only should add some comments to documentation about working with dummy
indices inside texmacs.

I repeat the test "ten_alg.dem" inside texmacs and for maxima-5.9.0
I see no problem and runtimes errors there. So, my conclusion is that there's
nothing wrong with itensor itself.
