We could use either the <restore> argument or a :keeppos modifier.
Both have advantages and disadvantages. I think the problem with
:keeppos is that this gives the idea that it works for all commands,
while only a few commands will actually support it.
On the other hand, for a command like :s, a <restore> argument isn't
really possible, would need to use a flag, which means different
commands have different ways to keep the position.
