 If you use Emacs as a daemon (e.g. starting it as `emacs --daemon` or calling `(server-start)`),
 you can change the `exec` command to invoke `emacsclient` directly.  Note that, since Emacsclient
 can’t actually write stuff to the terminal, it will output an Emacs string full of backslashes
 (see [this Emacs SE answer for details](https://emacs.stackexchange.com/a/28668/507)); thus, you
-have to pipe the output through `jq fromjson`. In this case, no output file will be written.:
