I had started a patch as well, but was interrupted by a meeting, so I 
didn't get very far.  Thanks for doing it!

The new message "Trace stopped on user request" looks good to me.

Should we prefer static_cast<int>() over (int)?

It might be a good idea to check that the resulting integer is smaller 
than the array size.  If we ever add new stop reasons, we could forget 
to add array elements, so an error() here would catch it.

Otherwise, LGTM.
