Notmuch uses a mix of 8 char width tabs and spaces.  First go tabs, then,
if you need indenting with more precision, spaces.  Look at the lines
your patch removes for an example.

Also, .dir-locals.el sets some variables to configure Emacs for Notmuch
coding style but only for c-mode.  You may set it by hand for lisp.
