Sorry to be a total PITA, but using "flags" plural suggests that it only
returns true if there is more than one exclude flag set.
A better name would be event_has_exclude_flag() or maybe
event_has_any_exclude_flag().
If you're doing a respin anyway it'd be nice to fix the name, but
obviously it's not high priority.
cheers
