+> Add customize options for deleted/added tag formats. These are not\r
+> used yet but will be later in the series.\r
+> \r
+> We switch to using `notmuch-apply-face' rather than `propertize' in\r
+> the defcustom for faces so that the faces for deleted/added tags add\r
+> to the default face attributes for the tag.\r
+> \r
+> We special case deleting the unread tag as that tag is a strong visual\r
+> cue and we don't need that cue when we are just saying it used to be\r
+> unread. Thus, we revert to the normal tag face with strikethough for\r
+> deleted unread tags.\r
