Scan should not throw on empty sequences #97
Description
The Scan<T> implementation throws when an empty sequence is found. I believe
the correct behavior should be to yield break in that case.
This would mean a different behavior from the Scan<T, TState> implementation,
but it is already different. Without a seed, an IEnumerable of size N will
yield an IEnumerable of the same size, while the version with seed adds an
extra element.
So making a 0-length IEnumerable result in a 0-length IEnumerable seems like
the right behavior to me.
