new snapshot available: coreutils-7.5.65-61cc6

[Jim Meyering]

There have been disproportionately many bug fixes since coreutils-7.5.
It's an interesting mix of fixes for recent regressions and for a few older 
bugs.

There have been many changes in gnulib, too, and this snapshot
includes the very latest.  I expect to release coreutils-7.6 on
Thursday or Friday.

Here's the NEWS I expect to see for coreutils-7.6:

** Bug fixes

  cp, mv now ignore failure to preserve a symlink time stamp, when it is
  due to their running on a kernel older than what was implied by headers
  and libraries tested at configure time.
  [bug introduced in coreutils-7.5]

  cp --reflink --preserve now preserves attributes when cloning a file.
  [bug introduced in coreutils-7.5]

  cp --preserve=xattr no longer leaks resources on each preservation failure.
  [bug introduced in coreutils-7.1]

  dd now exits with non-zero status when it encounters a write error while
  printing a summary to stderr.
  [bug introduced in coreutils-6.11]

  df no longer requires that each command-line argument be readable
  [bug introduced in coreutils-7.3]

  ls -i now prints consistent inode numbers also for mount points.
  This makes ls -i DIR less efficient on systems with dysfunctional readdir,
  because ls must stat every file in order to obtain a guaranteed-valid
  inode number.  [bug introduced in coreutils-6.0]

  tail -f (inotify-enabled) now flushes any initial output before blocking.
  Before, this would print nothing and wait: stdbuf -o 4K tail -f /etc/passwd
  Note that this bug affects tail -f only when its standard output is buffered,
  which is relatively unusual.
  [bug introduced in coreutils-7.5]

  tail -f once again works with standard input.  inotify-enabled tail -f
  would fail when operating on a nameless stdin.  I.e., tail -f < /etc/passwd
  would say "tail: cannot watch `-': No such file or directory", yet the
  relatively baroque tail -f /dev/stdin < /etc/passwd would work.  Now, the
  offending usage causes tail to revert to its conventional sleep-based
  (i.e., not inotify-based) implementation.
  [bug introduced in coreutils-7.5]

** New features

  cp --reflink accepts a new "auto" parameter which falls back to
  a standard copy if creating a copy-on-write clone is not possible.
