Git doesn't know which branch is 'main'. But that's okay. Git bisects
the DAG, not any particular linear commit chain.
This can be surprising if you're not expecting it. For example, if you
have two roughly equal length branches that you just merged, bisecting
just before the branch to just after the merge will likely choose a
commit right before the merge, only a few commits back in the history.
But this is good because testing that commit will eliminate one of the
branches (and therefore half of the commits), and then git will bisect
the other one the way you'd expect.
