Rn bug patch #15 (REPOSTED)

[Jonathan Biggar]

System: rn version 4.1
Bug #: 15
Priority: LOW
Subject: (Mail) happens inappropriately.
Index: ng.c
Prereq: 4.1.1.2
From: mp at allegra.UUCP

Description:
	Since (at least here) people frequently keep messages in their
	mailboxes for weeks at a time, the (Mail) prompt is a bit
	misleading.  I changed it so that the prompt appears only if the
	mailbox contains unread mail.

Fix:	From rn, say "| patch -d DIR", where DIR is your rn source directory.
	Outside of rn, say "cd DIR; patch <thisarticle".  If you don't have
	the patch program, apply the following by hand, or get patch.

	This patch must be applied only to a revision 4.1.1.2
	ng.c (with patch #10 applied).
