bug#23022: new snapshot available: gzip-1.6.51-989e

From: Jim Meyering
Subject: bug#23022: new snapshot available: gzip-1.6.51-989e
Date: Tue, 15 Mar 2016 11:52:18 -0700

We're close to releasing gzip-1.7.
Since the preceding snapshot, there have been some portability
fixes directly in gzip sources, as well as many we've pulled in
via an update from gnulib. Please let us know if you test.
I'd like to make the release no later than this weekend.

gzip snapshot:

Here are the current NEWS entries
(unchanged since the preceding snapshot):
** Changes in behavior

  The GZIP environment variable is now obsolescent; gzip now warns if
  it is used, and rejects attempts to use dangerous options or operands.
  You can use an alias or script instead.

** New features

  gzip now accepts the --synchronous option, which causes it to use
  fsync and similar primitives to transfer output data to the output
  file's storage device when the file system supports this.  Although
  this option makes gzip safer in the presence of system crashes, it
  can make gzip considerably slower.

  gzip now accepts the --rsyncable option. This option is accepted in
  all modes, but has effect only when compressing: it makes the resulting
  output more amenable to efficient use of rsync.  For example, when a
  large input file gets a small change, a gzip --rsyncable image of
  that file will remain largely unchanged, too.  Without --rsyncable,
  even a tiny change in the input could result in a totally different
  gzip-compressed output file.

** Bug fixes

  gzip -k -v no longer reports that files are replaced.
