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:

# Extract version number into 4 parts, some of which may be empty:
#
# version: the numeric part of the most recent tag. Will always look like 1.3.
#
# type: if an rc build, "rc", otherwise empty
#
# distance: the distance from the nearest tag, or empty if built from a tag
#
# node: the node|short hg was built from, or empty if built from a tag
