You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: git.rb
    path of file: ./repos/dependabot-core/common/lib/dependabot/workspace
    
    the code of the file until where you have to start completion: # typed: strict
# frozen_string_literal: true

require "sorbet-runtime"
require "dependabot/workspace/base"
require "dependabot/workspace/change_attempt"

module Dependabot
  module Workspac
    
      def current_commit
        # Avoid emitting the user's commit message to logs if Dependabot hasn't made any changes
        return "Initial SHA: #{initial_head_sha}" if changes.empty?

        # Prints out the last commit in the format "<short-ref> <commit-message>"
        run_shell_command(%(git log -1 --pretty="%h% B"), allow_unsafe_shell_command: true).strip
      end
