+ user event and thus has all of its semantics -- e.g. being

+
+ The real issue here is that "user events" and "command events"
+ are not the same thing, but are very much confused in
+ event-stream.c. User events are, essentially, any event that
+ should be delayed by accept-process-output, should terminate a
+ sit-for, etc. -- basically, any event that needs to be processed
+ synchronously with key and mouse events. Command events are
+ those that participate in command building; scrollbar events
+ clearly don't belong because they should be transparent in a
+ sequence like C-x @ h <scrollbar-drag> x, which used to cause a
+ crash before checks similar to the is_scrollbar_event() call were
+ added. Do other events belong with scrollbar events? I'm not
+ sure; we need to categorize all misc-user events and see what
+ their semantics are.
+
+ (You might ask, why do scrollbar events need to be user events?
+ That's a good question. The answer seems to be that they can
+ change point, and having this happen asynchronously would be a
+ very bad idea. According to the "proper" functioning of
+ scrollbars, this should not happen, but XEmacs does not allow
+ point to go outside of the window.)
+
+ Scrollbar events and similar non-command events should obviously
+ not be recorded in this-command-keys, so we need to check for
+ this in next-event.
+

+ #### here, and later as a result of reset_this_command_keys().
