How do you fix a bad merge, and replay your good commits onto a fixed merge?
... the one described in the question. This recipe is for fixing a bad merge, and replaying your good commits onto a fixed merge.

What does the star operator mean, in a function call?
...
s = sum(1, 2)
The double star ** does the same, only using a dictionary and thus named arguments:
values = { 'a': 1, 'b': 2 }
s = sum(**values)
You can also combine:
def sum(a, b, c, d):
return a + b + c + d
values1 = (1, 2)

s = sum(*values1, **values2)
