+This changes `seen' to mean that the user viewed `enough' of the whole\r
+message: more precisely, a message is deemed seen if the top of the\r
+message and either the bottom of the message or a point at least some\r
+customisable number of lines into the message have each been visible\r
+in the buffer at some point.\r
+\r
+This is placed into the post-command-hook infrastructure introduced in\r
+the previous patch.\r
