Indeed.  And it's not the right choice in your case.  But I'm pretty
sure it is the right choice in other cases.

Maybe we should make move-to-column pay attention to stickiness so that
you con control where it stops by playing with text-properties's
stickiness (or overlay's insertion types).

But just changing the behavior from one side to the other will just fix
it in some cases and break it in others.
