+This enables fast navigation between hunks and better highlighting.\r
+\r
+The use of notmuch-get-bodypart-internal could be improved; hard\r
+coding to 1 seems to work for the output of git-format-patch. It also\r
+not so nice to call (insert (notmuch-get-bodypart-internal ...)) since the\r
+last thing n-g-b-i does is call buffer-string.\r

+This is a hacked version of which does seem to quit on q. The\r
+difficulty is that diff-mode sets minor-mode-overriding-map-alist to\r
+change the map when the buffer is read-only and it seemed to be\r
+difficult to override without affecting diff-mode maps globally.\r
+\r
+This should be safe in that respect. However, I don't know whether it\r
+is allowed to set a keymap to something within a "let" and what\r
+happens to it after we exit the let. I am also not completely sure\r
+about the lexical-let: but it was what diff-mode used to do this\r
+(those two lines are copied from diff-mode)\r
+\r
+Best wishes\r
