List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Thu, 04 Jul 2013 22:22:06 -0000 Recently notmuch-hello was converted to use batch count. However, it seems that several people run different versions of notmuch-emacs and notmuch-cli so this batch makes emacs fail with an error message if --batch is not available in the CLI. --- There have been two cases on irc of people getting backtraces when hitting this problem so it might be worth adding an informative error message.
