You're talking about a special case where (1) you've been at that line sometime
earlier, (2) you saved the position then, and (3) the new line is exactly the
same length as the old.

There are often such rare corener special cases that are possible for something
that isn't possible in general.

It's quite misleading to put that up as if it contradicted what I wrote.

For the general problem, it's the same in any language.
