This looks useful.  However, the current implementation appears
to change the order in which each kind of path is generated.
The order is very important and cannot be changed.

Instead you'll have to refactor the path generation to store
a boolean with each value that indicates whether it is to be
re-rooted or not.  Or, re-arrange the generation to construct
separate lists of paths from each source first, and then
combine them while re-rooting some.
