t/examples/streams.t broken by r37251

[coke]

The file examples/streams/FileLines warns:

=head1 NOTE

When updating this file, be sure to verify L<t/example/streams.t>, as its tests rely on the content of this file

---

That test now fails and needs to be re-updated with the contents of the file.

As long as this change is being made, please also update the L<> in the pod in the source file to the actual test path of

t/examples/streams.t

And add a period to that sentence.

[Util]

In r37295, the POD has been updated as requested, and the failing tests have been updated to match the changes from r37251.

The tests now pass.
