siggen: Ensure correct runtask dependency output is shown for diffsigs
PATCH 1/1 siggen: Ensure correct runtask dependency output is shown for diffsigs
The actual task names are discounted for comparison of dependent tasks, only the actual hashes are used. This updates the comparison code to account for this change, attempting heuristic matching for more user friendly output but falling back to showing the changed hashes directly. This avoids some confusing output to users where it looked like tasks had changed when they had not and actually had the same hash but a different taskname.
