pub fn unset_branch_base(branch: &str, verbose: bool) -> Result<()>Expand description
Clear a branch’s recorded base info (branch.<name>.gwBase and .gwBaseSha).
Each unset is a no-op (not an error) when the key is absent, so callers can
clear unconditionally — e.g. gw sync after restacking a branch onto the
default branch, where it is no longer stacked.
