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.
Best wishes
