template: compute verb in obsfateverb Add a template function obsfateverb which use the markers information to compute a better obsfate verb. The current logic behind the obsfate verb is simple for the moment: - If the successorsets is empty, the changeset has been pruned, for example: Obsfate: pruned - If the successorsets length is 1, the changeset has been rewritten without divergence, for example: Obsfate: rewritten as 2:337fec4d2edc, 3:f257fde29c7a - If the successorsets length is more than 1, the changeset has diverged, for example: Obsfate: split as 2:337fec4d2edc, 3:f257fde29c7a As the divergence might occurs on a subset of successors, we might see some successors twice: Obsfate: split as 9:0b997eb7ceee, 5:dd800401bd8c, 10:eceed8f98ffc; split as 8:b18bc8331526, 5:dd800401bd8c, 10:eceed8f98ffc
