Automatically syncing Gollum wiki when used as a web service. I've added the lines at 43, 44 to do a pull/push on the repo to automatically sync on git commit. Is there a cleaner way to do this? And what are the potential issues regarding conflicts?

wiki.rb

# Public: Write a new version of a page to the Gollum repo root.
    #
    # name - The String name of the page.
    # format - The Symbol format of the page.
    # data - The new String contents of the page.
    # commit - The commit Hash details:
    # :message - The String commit message.
    # :name - The String author full name.
    # :email - The String email address.
    # :parent - Optional Grit::Commit parent to this update.
    # :tree - Optional String SHA of the tree to create the
    # index from.
    # :committer - Optional Gollum::Committer instance. If provided,
    # assume that this operation is part of batch of
    # updates and the commit happens later.
    # dir - The String subdirectory of the Gollum::Page without any
    # prefix or suffix slashes (e.g. "foo/bar").
    # Returns the String SHA1 of the newly written version, or the
    # Gollum::Committer instance if this is part of a batch update.
    def write_page(name, format, data, commit = {}, dir = '')
      # spaces must be dashes
      name.gsub!(' ', '-')
      dir.gsub!(' ', '-')

      multi_commit = false

      committer = if obj = commit[:committer]
        multi_commit = true
        obj
      else
        Committer.new(self, commit)
      end

      filename = Gollum::Page.cname(name)

      committer.add_to_index(dir, filename, format, data)

      committer.after_commit do |index, sha|
        @access.refresh
        index.update_working_dir(dir, filename, format)
        
        # added to automate syncing
        @repo.git.native('pull')
        @repo.git.native('push')
        
      end

      multi_commit ? committer : committer.commit
    end
