[PATCH] lei p2q: document --uri, add examples

[Eric Wong <e@80x24.org>]

This is useful for users lacking in local storage.  Also,
referencing lei-add-external(1) seems to make less sense
than referencing lei-q(1).

We'll also stop dropping years from the copyright statement
to reduce future churn.
