cff070aba6 Fix exit status of xzgrep when grepping binary files.
When grepping binary files, grep may exit before it has
read all the input. In this case, gzip -q returns 2 (eating
SIGPIPE), but xz and bzip2 show SIGPIPE as the exit status
(e.g. 141). This causes wrong exit status when grepping
xz- or bzip2-compressed binary files.

The fix checks for the special exit status that indicates SIGPIPE.
It uses kill -l which should be supported everywhere since it
is in both SUSv2 (1997) and POSIX.1-2008.

Thanks to James Buren for the bug report.

40277998cb Scripts: Better fix for xzgrep.
Now it uses "grep -q".

Thanks to Gregory Margo.

c7210d9a3f Scripts: Fix xzgrep -l.
It didn't work at all. It tried to use the -q option
for grep, but it appended it after "--". This works
around it by redirecting to /dev/null. The downside
is that this can be slower with big files compared
to proper use of "grep -q".

Thanks to Gregory Margo.

96e4b257e1 Major update to the xzgrep and other scripts based on
the latest versions found from gzip CVS repository.

configure will try to find a POSIX shell to be used by
the scripts. This should ease portability on systems
which have pre-POSIX /bin/sh.

xzgrep and xzdiff support .xz, .lzma, .gz, and .bz2 files.
xzmore and xzless support only .xz and .lzma files.

The name of the xz executable used in these scripts is
now correct even if --program-transform-name has been used.
