+\r
+I thought about this a bit more (mostly because I don't want to write\r
+tests for one behaviour and then have to change them - writing tests for\r
+emacs with the current test suite is painful).\r
+\r
+If you want to go back a page you can use M-v. The whole point of\r
+binding DEL to something in `notmuch-show-mode' is that it implement\r
+something other than the vanilla behaviour. Simply showing the previous\r
+page (the equivalent of M-v) adds no value.\r
+\r
+Hence, I'd like to keep the (jump back a full message) behaviour in the\r
+patch.\r
