Upstream update:

* Noteworthy changes in release 2.9 (2010-02-11) [stable]

** New features

 New diff option --suppress-blank-empty.

 Bring back support for `diff -NUM', where NUM is a number,  even when conforming to POSIX 1003.1-2001.  This change reverts to  the behavior of GNU diff 2.7 and earlier.  This is a change only  when conforming to POSIX 1003.1-2001; there is no effect when  conforming to older POSIX versions.

 This change is in response to decisions taken in the January 2005  Austin Group standardization meeting.  For more details, please see  "Utility Syntax Guidelines" in the Minutes of the January 2005  Meeting <http://www.opengroup.org/austin/docs/austin_239.html>.

 sdiff now understands '1' and '2' as synonyms for 'l' and 'r'.

** Changes in behavior

 sdiff and diff3 now invoke diff, not $(bindir)/diff

** Administrivia

 New discussion and bug-reporting address: bug-diffutils@gnu.org

 updated gnulib support
