In the way git weighs merge bases, there actually can be two "best" ones, which means two of the same quality. But I agree that the wording is confusing, so maybe "all suitable" should be used?

I think the git subcommand pages are not consistent in this matter, but the majority uses just commit.

It means that consistency should be fixed. For instance we can write script to do that like in #9578 PR.


- Check if a commit is an ancestor of a specific commit:

`git merge-base --is-ancestor {{ancestor_commit}} {{commit}}`
