It shouldn't ever exceed N, as N should grow larger if M grows past it.
However, yes. N is not fixed, because it is only an estimate, which can
be updated.

Specifically, it is a fairly good estimate if you are working with a
long lived branch, but not for an initial import of a large branch
(little history, lots of file content).
