We have a feature branch "feature" that has many descendant branches that are not merged in. I would like to find all of these branches so that we can make decisions to merge them in or not. We have a fairly large git repository and using git branch feature --no-merge shows us hundreds of branches that are not descendants of "feature".
I know that git does not track parent branches so this seems to be a difficult task and I was wondering if anyone has an easy way to find these.
