[boost] [msm] orthogonal region and event consume

Hello Christophe, I'm using Boost.MSM version 1.49.0. I bumped on a suspicious behavior. See the attached diagram and code. When Event1 occurs in State1, Action1 is invoked. I think the event isn't consumed correctly. If the transition from State1 to State2 connect State2 directly instead of Entry1, the event seems to be consumed. What do you think? Thanks, Takatoshi
