coreutils-6.9.90 released

Coreutils version 6.9.90 has been released.
This is a feature release, but it includes a surprising number
of fixes for very old bugs.

If you haven't heard about the GNU coreutils, the FAQ is a good
place to start: <http://www.gnu.org/software/coreutils/faq/>.

It's been more than 8 months and almost 450 change-sets since the
previous release, which was the stable coreutils-6.9, on 2007-03-22.
Like coreutils-6.8, I consider this a not-unstable release.  I can't in
good conscience call it stable, because there have been so many changes
and not enough exposure, yet I have a lot of confidence that the programs
are consistently improved over the ones in coreutils-6.9.

Thanks to everyone who has contributed to this release.  Here's the list
of 'commit author' names and commit counts, excluding mine.  If you sent
