+ build: avoid automake warning that suggests use of subdir-objects
+ * configure.ac (AM_INIT_AUTOMAKE): Use the subdir-objects option.
+
+ build: avoid warning about deprecated use of automake's ACLOCAL_AMFLAGS
+ * Makefile.am (ACLOCAL_AMFLAGS): Don't use this deprecated variable.
+ * configure.ac: Do this instead: AC_CONFIG_MACRO_DIR([m4]).
+
+ build: use more portable shell syntax in search of working shell
+ * m4/shell.m4: Adjust sh/case syntax not to evoke a syntax
+ error from Solaris 10's /bin/sh.
+
+ build: update gnulib to latest, and bootstrap

+2013-05-28 Jim Meyering <meyering@fb.com>

+2013-05-28 Rodrigo Campos <rodrigo@sdfg.com.ar>
+
+ gzip: add "--keep" option to retain (don't delete) input files
+ gzip now accepts the --keep (-k) option, for consistency with tools
+ like xz, lzip and bzip2. With this option, gzip no longer removes
+ named input files when compressing and decompressing.
+ * doc/gzip.texi: Document it.
+ * gzip.1: Likewise.
+ * gunzip.in: Likewise.
+ * NEWS: Likewise.
+ * gzip.c: Add support for "--keep".

+ * tests/help-version (zdiff_setup, zcat_setup, znew_setup, zgrep_setup)
+ (gzexe_setup): Pass --__bindir so that subsidiary programs are our

+ (zcmp_setup, gunzip_setup, zmore_setup, zless_setup, zforce_setup)

+
+ maint: adjust to Gnulib, Automake changes

+
+ build: default to --enable-gcc-warnings in a git tree
+ Anyone building from cloned sources can be assumed to have a new

+2012-08-14 Paul Eggert <eggert@cs.ucla.edu>
+
+ zgrep: do not assume GNU expr
+ * zgrep.in: Do not assume '\+' has the GNU behavior in the BRE
+ given to 'expr', as POSIX does not guarantee that. Come to think
+ of it, use a shell pattern rather than 'expr', as this is more
+ efficient.

+ zmore: rewrite to fix bugs and assume POSIX
+ Problem reported for Solaris 9 by Daniel in
+ <http://lists.gnu.org/archive/html/bug-gzip/2012-06/msg00007.html>.
+ Rather than figure out what exactly went wrong in Solaris 9
+ it was easier to rip out all the buggy compatibility and stty cruft.
+ * zmore.in: Don't use stty or trap; simply pipe the output to 'more'
+ and let it deal with signals and terminal control.
+ Use printf, not 'echo', to avoid problems with backslashes.
+ Don't assume ANS is not 's' in the environment.
+ Use a 'more'-style header instead of rolling our own style.
+ Paginate the header, too; the old behavior lost the header.
+ * NEWS, zmore.1: Document this.
