+
+ zgrep: don't assume traditional behavior with signal numbers
+ * zgrep.in: Don't assume the exit status is the signal number plus
+ 128, as POSIX doesn't require this. No need to kill self; exiting
+ with large status is enough. Propagate all exit statuses greater
+ than 1, not merely those in the range 129..143, as there's no need
+ to treat that range specially (and it's not portable anyway).
+
+2010-11-09 Paul Eggert <eggert@cs.ucla.edu>
+
+ zgrep: fix shell portability bug with -f; fix mishandling of "-e -"
+ * tests/zgrep-f: Check for "zgrep -e -" bug, too.
+ * zgrep.in: Don't assume that if the shell redirects fd 6, then
+ this redirection is visible to the subsidiary grep. POSIX doesn't
+ guarantee this visibility except for file descriptors 0, 1, and 2,
+ and ksh does not support it. Problem reported by Thomas Schulz in
+ <http://lists.gnu.org/archive/html/bug-gzip/2010-11/msg00000.html>.
+ Also, fix a related bug: "-e -" was mishandled. These two bugs
+ were introduced by commit 5b54db4546b84ec97ff57a62f8ddb98faacf77f2
+ dated 2009-10-09.
+ (escape): Change the convention: do not assume that a stray X
+ is present at the end of the last line. All uses changed.
+ There was no longer any need for this convention, and fixing this
+ made it a bit easier to use 'sed' in a later part of the fix.

+2010-11-08 Paul Eggert <eggert@cs.ucla.edu>

+ maint: fix copyright dates that were munged by a maintenance script
+ * gunzip.in, gzexe.in, zcat.in, zcmp.in, zdiff.in, zforce.in:
+ * zgrep.in, zless.in, zmore.in, znew.in:
+ A script went awry when updating copyright dates in gzip's shell
+ scripts. It should update comments to look like "# Copyright (C)
+ 2007, 2010 Free Software Foundation, Inc." (with a set of years)
+ and version messages to look like "Copyright (C) 2010 Free
+ Software Foundation, Inc." (with just the most-recent year).
+ Instead, it sometimes ignored one, sometimes the other, and
+ typically put ranges into version messages. Fix all this stuff by
+ hand, using dates that I divined from the change logs (so they're
+ a bit more accurate than script-generated dates). We need to fix
+ the script before it runs in 2011.

+ This was introduced via 2009-12-17 commit 0341fc22,
+ "build: with --enable-gcc-warnings, use -Werror",

+ it would have overridden was always empty.
+
+2010-01-10 Jim Meyering <meyering@redhat.com>
+
+ gzip -d would fail with a CRC error...
+ ...for some inputs, and some memcpy implementations. It is possible
+ that an offending input has to be compressed "from FAT filesystem
+ (MS-DOS, OS/2, NT)", since the sole reproducer no longer evokes a
+ CRC error when uncompressed and recompressed on a GNU/Linux system.
+ Also, using an unpatched reverse-memcpy-gzip on over 100,000 inputs
+ on a GNU/Linux system did not turn up another reproducer.
