new snapshot available: coreutils-7.0.171-0dc44

[Jim Meyering]

Here's a snapshot of the latest from coreutils,
along with the parts of gnulib it uses.

coreutils snapshot:

  http://meyering.net/cu/coreutils-7.0.171-0dc44.tar.xz

Note the new .xz suffix.  I've switched to XZ, the new name for lzma,
to go with some new functionality and a stable format.[1]

With over 100 change sets since the last snapshot, it was overdue.
Here's what's changed in NEWS, followed by a "git shortlog" summary:

Since there have been so few real bugs, and there has been relatively
little change in existing code (excluding non-invasive feature addition),
I expect to declare the next release "stable".  FYI, fewer than 20 of
the shortlog summaries listed below represent potentially destabilizing
changes.  Most are adding tests, documentation, or performing some sort
of clean-up or maintenance.

Thanks to everyone who's been contributing!

 ** New features

+  Add extended attribute support available on certain filesystems like ext2
+  and XFS.
+    cp: Tries to copy xattrs when --preserve=xattr specified
+    mv: Always tries to copy xattrs
+    install: Never copies xattrs
+
+  cp and mv accept a new option, --no-clobber (-n): silently refrain
+  from overwriting any existing destination file
+
+  dd accepts iflag=cio and oflag=cio to open the file in CIO (concurrent I/O)
+  mode where this feature is available.
+
   ls --color now highlights hard linked files, too

   stat -f recognizes the Lustre file system type

 ** Bug fixes

+  chgrp, chmod, chown --silent (--quiet, -f) no longer print some diagnostics
+  [bug introduced in coreutils-5.1]
+
+  cp uses much less memory in some situations
+
+  du --files0-from=FILE no longer reads all of FILE into RAM before
+  processing the first file name
+
   seq 9223372036854775807 9223372036854775808 now prints only two numbers
   on systems with extended long double support and good library support.
   Even with this patch, on some systems, it still produces invalid output,
   from 3 to at least 1026 lines long. [bug introduced in coreutils-6.11]

+  wc --files0-from=FILE no longer reads all of FILE into RAM, before
+  processing the first file name, unless the list of names is known
+  to be small enough.
+
 ** Changes in behavior

+  cp and mv: the --reply={yes,no,query} option has been removed.
+  Using it has elicited a warning for the last three years.
+
+  dd: user specified offsets that are too big are handled better.
+  Previously, erroneous parameters to skip and seek could result
+  in redundant reading of the file with no warnings or errors.
+
+  du: -H (initially equivalent to --si) is now equivalent to
+  --dereference-args, and thus works as POSIX requires
+
+  shred: now does 3 overwrite passes by default rather than 25.
+
   ls -l now marks SELinux-only files with the less obtrusive '.',
   rather than '+'.  A file with any other combination of MAC and ACL
   is still marked with a '+'.
