i know that it's an iter_ctrl detail, but nevertheless the branch 
tracer (which is how people will be using this) should have some 
self-test.

it might also make sense to just have a standalone 'branch' tracer 
plugin as well. We have all the callbacks in place already, and people 
might be interested in just that info - not in some other tracing 
output.
