I don't know the svn code at all... but I expect it is analogous to a baton that relay race team uses. The first person starts running with the baton... he runs his leg and passes the baton to the next runner on the team... who takes it through his part of the course.

So, I would expect that a baton is some symbol or reference to an object that is passed from one function to another and each function performs its responsibility modifying the baton or possible using information stored in the baton.
