diff-mode bug

[Amit Shah]

In GNU Emacs 21.2.1 (i386-debian-linux-gnu, X toolkit, Xaw3d scroll bars)
 of 2002-03-22 on raven, modified by Debian
configured using `configure  i386-debian-linux-gnu --prefix=/usr
--sharedstatedir=/var/lib --libexecdir=/usr/lib --localstatedir=/var/lib
--infodir=/usr/share/info --mandir=/usr/share/man --with-pop=yes --with-x=yes
--with-x-toolkit=athena --without-gif' Important settings:
  value of $LC_ALL: nil
  value of $LC_COLLATE: nil
  value of $LC_CTYPE: nil
  value of $LC_MESSAGES: nil
  value of $LC_MONETARY: nil
  value of $LC_NUMERIC: nil
  value of $LC_TIME: nil
  value of $LANG: C
  locale-coding-system: nil
  default-enable-multibyte-characters: t

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

in the 'diff-mode', pressing 'R' should convert:

--- xxx
+++ yyy

to

--- yyy
+++ xxx

but this only works for the 1st hunk.

The other hunks are marked as

-++
+--

or

--+
+--

or some other patterns. It is not a fixed pattern...
I produced the diff file by the 'cvs diff -u' command, and
removed the RCS: lines.
