Not sure if we need to hardcode the path to notmuch binary (some people
can use guix for managing emacs packages, but not system), but I think
it's a rare case and this default is reasonable and easily fixable by
simple `(setq notmuch-command "notmuch")` in the cases, when notmuch
itslef provided by other package manager.

Overall, LGTM.
