very minor grammatical error

[christopher-barry]

"where the master branch was on the person’s repository you cloned
from when you did so, and a master branch that points the most
recent local commit."

should be:
"where the master branch was on the person’s repository you cloned
from when you did so, and a master branch that points TO the most
recent local commit."
