First, giving an answer for more than one event is impossible for "C-h c"; not without a complete redesign of how we present the results.  Until very recently, we would show only the first event, which is useless for 90% of mouse clicks, since very few commands are bound to down-events.  This has been a source of constant annoyance for me for years, and now is finally solved.  So this is some progress.

For "C-h k", we probably should indeed show all the events, but the previous solution to show the down-event first was problematic here as well, as it showed the much less important event first, and a user who is in a hurry might not pay attention to the rest.

In most cases, there are 2 or less events to show, so Alan's patch that tells users how to get help on the down-event is a good stopgap, IMO.  In general, we should probably redesign how these multiple events are described, but that's a job for master, not for the release branch.
