ready for a new release?

[Jim Meyering]

I know of no pending work or bugs, and it's been almost 7 months
(long by my standards), so I'm ready.

Here's NEWS:

** Bug fixes

  gzip -d now decodes and checks header CRC16 checksums as specified by
  the FHCRC section of Internet RFC 1952.

  "gzip -d -S '' precious.gz" is now rejected immediately.  Before,
  that command would emulate "rm -i precious.gz", but with an easily-
  misunderstood prompt.  I.e., gzip would ask if it's ok to remove the
  existing file, "precious.gz".  If you made the mistake of saying "yes",
  it would remove that input file before attempting to uncompress it.

  gzip -cdf now properly handles input consisting of gzip'd data followed
  by uncompressed data.  Before it would output raw compressed input, too.
  For example, now "(printf x|gzip; echo y)|gzip -dcf" prints "xy\n",
  while before it would print "x<compressed data>y\n".

  gzip -rf no longer compresses files more than once (e.g., replacing
  FOO with FOO.gz.gz) on file systems such as ZFS where a readdir
  loop that unlinks and creates files can revisit output files.
