It's an optimization, we have already calculated the merge base above in 
the "onto" calculation when --keep-base is given. This is what I meant 
by "avoid calculating the merge-base twice when --keep-base is given" in 
the commit message, maybe I should  try and come up with some clearer 
wording.

Best Wishes

Phillip
