All what would have to be done is to change at w= hat *cursor* position the selection jumps to the next character (namely whe= n it crosses its middle).

As long as the changes are one character at a > time, there's no way around that basic fact. Yes, it will still be off -- but only half as far. This makes a big differe= nce in terms of interaction. Checking other editors, they do it the same, and I think that is what is th= e "expected behaviour".
