2302 3) When G4Navigator's ComputeStep returned 971 3) When G4Navigator's ComputeStep returned stepLength==stepRequested, this
2303 used to be treated as a failure to intersect. 972 used to be treated as a failure to intersect. This is incorrect.

2305 stepLength==stepRequested is an intersect 974 stepLength==stepRequested is an intersection,
2306 so I am now treating it as such in each 975 so I am now treating it as such in each comparison (of 3).
