rn 4.3 patch #26

[Larry Wall]

System: rn version 4.3
Patch #: 26
Priority: LOW
Subject: Catch command can throw off unread article count
From: msb at lsuc.UUCP (Mark Brader)

Description:
	If more articles are found for a newsgroup after a catchup command
	has been executed, the count of unread articles will be off.  This
	is a hangover from when catchup always threw you out of the newsgroup,
	so it didn't bother keeping track of unread articles because it knew
	it would be recomputed later.

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.

	If patch indicates that patchlevel is the wrong version, you may need
	to apply one or more previous patches, or the patch may already
	have been applied.  See the patchlevel file to find out what has or
	has not been applied.  In any event, don't continue with the patch.
