//! Implements `limb lock`. Locks a worktree against prune and remove.

/// Runs `limb lock`.
///
/// Locks the named worktree via `git worktree lock`, optionally recording
/// the `--reason` (shown in `git worktree list`).
///
/// # Errors
///
/// Returns an error if the name does not match or the git invocation
/// fails (e.g. the worktree is already locked).
