pub fn set_branch_base(branch: &str, base: &str, verbose: bool) -> Result<()>Expand description
Record the base branch a branch is stacked on (branch.<name>.gwBase).
Lets the workflow know a branch is stacked before its PR exists, so
gw status can suggest gh pr create -B <base>. Git drops the whole
[branch "<name>"] section when the branch is deleted, so this needs no
explicit cleanup on gw cleanup.
