26562973b3482a635416b2b663a13016d4d90e20 is an ancestor of the bad
commit, and not an ancestor of the good commit, thus it is a candidate
for introducing the bad condition.  In a non-linear history, there can
be multiple good commits that are not directly related, each one cutting
out branches from the history.
