Good work! It would be nice if the state file contained newline after
count number. Also some optimizations could be done:

		cat >"$notmuch_counter_command" <<EOF || return
#!/bin/sh

read count < "$notmuch_counter_state_path"
echo \$((count + 1)) > "$notmuch_counter_state_path"

exec notmuch "\$@"
EOF
		chmod +x "$notmuch_counter_command" || return
	fi

	echo 0 > "$notmuch_counter_state_path"
}

# Returns the current notmuch counter value.
notmuch_counter_value () {
	if [ -r "$notmuch_counter_state_path" ]; then
		read count < "$notmuch_counter_state_path"
	else
		count=0
	fi
	echo -n $count
}
