"Should Imenu display messages indented.
By default, Imenu (see Info node `(emacs) Imenu') in a
notmuch-show buffer displays all messages straight. This is
because the default Emacs frontend for Imenu makes it difficult
to select an Imenu entry with spaces in front. Other imenu
frontends such as counsel-imenu does not have this limitation.
In these cases, Imenu entries can be indented to reflect the
position of the message in the thread."
