i understand that branch is like a "sticky-note" where the commit ID is overwritten when user makes new commits on that branch. The basis for my actual question was to find the latest fork point off the main branch, so that i can find if a specific commit is present on a branch (which was created off main).
For instance if "main" branch has a commit (ID: 4356hae), how to list out the branches that containing his content/commit ID?
