7d55409b82 pgrep: use sigqueue to pass value with the signal.
Based on the command line option, use 'sigqueue'
instead of 'kill' to pass the integer value with
the signal.

625d0809da pkill: Return 0 if successfully killed process
Original report:
When trying kill a process with insufficient privileges (see blow),
pkill displays the error message “... failed: Operation not permitted”,
but returns 0. Surely it should return 3?

$ pkill syslogd ; echo $?
pkill: killing pid 373 failed: Operation not permitted
0

Return value 0 means one of more things matched. For a pgrep (which
shares code with pkill) this makes sense, there was a match. It seems
wrong for pkill to return 0 when it in fact could not do what you told
it to.  However return value 3 means a fatal error and it's not fatal.

Looking at other programs when trying to kill things it cannot kill.
shell kill returns 1, procps kill returns 1, killall returns 1, skill
returns 0 (and says it was successful!, ah well poor old skill)

The consensus seems to be that you return 1 if you cannot kill it, even
if you found it. In other words the return value for both not found and
not able to kill it is the same.

pkill only returns 0 if something was killed. This means we found a
match AND the kill() system call worked too.

9742c74e7c pgrep: Enable case-insensitive process matching
FreeBSD has case-insensitive matching of processes in pgrep and
pkill, which can be super-useful. This patch uncomments and
documents the code needed to make this work.

fd77ca1dc6 pgrep.1 removed STANDARDS section
pgrep got updated due to the confusion of the f,l and a flags.
While the newer behaviour is far better but it is no longer following
the ancient Solaris standards, so that got removed.

de7b3b9222 pgrep: introduce support for namespaces
A PID should be specified with --ns:
	$ pgrep --ns 12345
which will only match the processes which belong to to the same 6
namespaces. It is also possible to specify which namespaces to test:
	$ pgrep --ns 12345 --nslist mnt,net,ipc
which will match processes that belong to the same mount, network and
IPC namespaces as PID 12345.

fe75e26ab6 miscellaneous: clean up trailing whitespace throughout
The entire tree's polluted with inappropriate trailing
whitespace. This commit rids our environment of all of
those useless keystrokes. Unfortunately, it sure ain't
a permanent solution and requires every contributor to
instruct their editor(s) to prevent or eliminate them.

Plus it's strongly recommended we all insert something
like what's shown below to our '.gitconfig' file so as
to provide at least some warnings when we try to apply
any patches (git am) that do contain the #@!%& things!

References(s):

  whitespace = trailing-space, space-before-tab, blank-at-eof

ce95dd53eb Add -c count option to pkill
Possibly by a side-effect but pkill -c option used to work which would
print the number of killed processes.  This small change restores this
functionality.

47100a8125 docs: fix manual page warnings
All warnings where about unnecessary quoting.  The scriptlet
below will tell what was wrong.

for I in ./top/top.1 ./ps/ps.1 ./*.[0-9]; do
    echo "== $I warnings =="
    man --warnings=all $I > /dev/null
done

This should probably be turned to 'make check' script.
