4d89280c8b Fix extra padding in 1-symbol reductions 
We were not taking into account the padding we had added on previous
iterations, and so we kept adding more and more for each reduction.

This was possible since e70b23208ac27f93a914fea77ec158c47ab9a389 and
a8155ad01cf575b99b9be08820bfb8ae9bdf337e and was unfortunately forgotten
in 53c7e620c90f38204aea5ec5ad6a4a7598a8a3ec :)
