+
+maildrop adds a newline to mbox files before delivering new messages.
+This effectively alters the final message in the mbox, causing a
+running mutt (and maybe other MUAs) with that mbox open to freak out
+and lose unsaved state [1]. The maildrop folks prefer to keep this
+(out of spec) behaviour to keep from breaking users working
+configurations as well as to avoid problems caused by other out of
+spec mail delivery agents (which may aberrantly neglect to leave a
+blank line at the end of the mbox) [2].
+
+This patch disables this behaviour of maildrop allowing an MUA to
+gracefully handle the delivery of new mail to an open folder.
