Bug #: 20
Subject: KILL files blow up because '/' not considered a metacharacter
Index: artsrch.c
From: ber at yquem.UUCP

Description:
	When rn is processing subjects to turn them into search strings, it
	translates search meta-characters into '.'.  Unfortunately, '/',
	while not strictly a search meta-character, is the search string
	delimiter used by the 'K' command, and needs to be included in the
	list of special characters.  (Note that '?' does not need to be
	a special character since 'K' only uses '/'.)

Repeat-By:
	Find an article with a subject containing a slash.  Type 'K' to put
	the subject into the KILL file.  Type '-' to get back to the article
	and 'm' to mark it unread.  Exit the newsgroup and reenter it.
	Watch the fireworks as rn tries to interpret the end of the subject
	as a list of commands.

Fix:	Install either artsrch.c.20-c (diff -c) by hand or artsrch.c.20-e
	(diff -e) using ed.  The -e version must be applied only to a stock
	revision 4.1 artsrch.c.

	To repair a KILL file with this problem, edit the KILL file, find
	the offending '/', and either quote it with a backslash, or replace
	it with a '.'.

Bug #: 21
Subject: filexp (the shell script) doesn't do ~/ or ~ right.
Index: Configure
From: steven at mcvax.UUCP (Steven Pemberton)

Description:
	There is a little shell script spit out by Configure to do tilde (~)
	substitution on systems that don't have csh.  Unfortunately, it
	doesn't do ~ or ~/* correctly if your home directory name happens
	to contain a slash (heh heh).

Repeat-By:
	Say "filexp ~".

Fix:	You can change this either in Configure or in filexp itself as you
	see fit.
Change

  : expand filename
  case $1 in
  ~/*|~)
!     /bin/echo $1 | /bin/sed "s/~/${HOME-$LOGDIR}/"
      ;;
  ~*)
      if /bin/test -f /bin/csh; then

to

  : expand filename
  case $1 in
  ~/*|~)
!     /bin/echo $1 | /bin/sed "s|~|${HOME-$LOGDIR}|"
      ;;
  ~*)
      if /bin/test -f /bin/csh; then

unless your home directory happens to contain '|', which I doubt.

Bug #: 22
Subject: unread article count can get off when articles expire
Index: bits.c
From: uddeborg at chalmers.UUCP (G|ran Uddeborg)

Description:
	Rn makes a faulty assumption about the read/unread status of
	certain expired articles when entering a newsgroup, with the
	result that the number of articles reported as remaining to be read
	will be low, and possibly even negative.  This doesn't hurt anything
	in particular, but it is somewhat disconcerting.

Repeat-By:
	Find a newsgroup in which the first existing article is followed
	by a range of expired articles.  If for instance, you have a newsgroup
	in which article 100 exists, as well as articles 200-300, edit your
	.newsrc to read:

	net.blurfl: 1-100,110-190,200-299

	If you then enter this newsgroup with rn, in trying to process
	expired articles 101-199 it will forget that you have read 110-190,
	and count them twice when it marks 101-199 as read.  In this example
	you would end up with rn saying there are about -80 unread articles.

Fix:	Install either bits.c.22-c (diff -c) by hand or bits.c.22-e (diff -e)
	using ed.  The -e version must be applied only to a stock revision
	4.1 bits.c.
