ok, there is a little trick in this.
Actually it is already used 1 char of separator for the longest possible opcode that is NOOP (undocumented), so all the others get 2 chars for having the right alignment (this is why 2 was the min allowed).
In this case I will have to "force" that when 1 char is used, NOOP potentially will break the aligment (but this will not be a problem as it not have operands) and comments should adjust themself.
