Need to say anything about redirect_user hint being a no-op if requesting party is non-human?

[xmlgrrl]

In Section 3.4.1.2 of Core, currently we say nothing about redirect_user being applicable only to end-user requesting parties. Do we need to add something about this, or is it obvious? It's just a hint, after all.

In UMA telecon 2015-02-19, we agreed to add this sentence: "Note that the word "user" implies a human requesting party; if the requesting party is not an end-user, then no client action would be possible on receiving the hint." Added to Core rev 12a.
