+In the new reply code, the References header gets inserted by\r
+message.el using a function called message-shorten-references. Unlike\r
+all the other header-inserting functions, it doesn't put a newline\r
+after the header, causing the next header to end up on the same\r
+line. In our case, this header happened to be User-Agent, so it's hard\r
+to notice. This is probably a bug in message.el, but we need to work\r
+around it.\r
+\r
+This fixes the problem by wrapping message-shorten-references in a\r
+function that inserts a newline after if necessary. This should\r
+protect against the message.el bug being fixed in the future.\r
