ps previously followed the Unix98 standard when it comes to
user-defined output, sometimes. This meant you could have
user output format with a header that included commas and
equals signs. It was dependent on if ps thought you wanted
sysv or bsd format and THAT was dependent on things in previous
options.
It was very confusing to a user because
ps p $$ -o pid=,comm=
gave you a two-column output but
ps -p $$ -o pid=,comm=
would give you a one column output with the header ",comm="
The -p versus p means (to ps) you want sysv or bsd parsing.
Unix98 standard or not, this is plainly just silly.
The commit removes any of the quirks Unix98 has with user defined
output. If you really wanted a ps header with commas in the output,
today isn't your day.

This patch was made necessary by those library changes
in support of recently revised/simplified wchan logic.
In addition, this commit eliminates a broken alternate
'namelist' provision which was intended to allow users
to specify a System.map file to be used in translating
addresses into function names. But, the real effect of
the now defunct 'N' and '-n' options was to indirectly
force addresses (not names) to be displayed since such
user named map files could not be successfully parsed.
Besides when the required FRAME_POINTER kconfig option
is absent there is no address to translate and when it
is present /proc/PID/wchan is already translated. Thus
an alternate mapping is unnecessary and inappropriate.
[ we'll forgive POSIX for documenting '-n namelist' ]

It doesn't make any sense to have the binary version strings
embedded into the library. The version strings are defined
already either in the Makefile or in include/c.h
This commit introduces a new option q/-q/--quick-pid
to the 'ps' command. The option does a similar job
to the p/-p/--pid option (i.e. selection of PIDs
listed in the comma separated list that follows
the option), but the new option is optimized
for speed.
In cases where users only need to specify a list
of PIDs to be shown and don't need other selection
options, forest type output and sorting options,
the new option is recommended as it decreases
the initial processing delay by avoiding reading
the necessary information from all the processes
running on the system and by simplifying
the internal filtering logic.
We got a bug report, that our project doesn't spell "SELinux"
consistently/correctly. I've fixed that and the patch is attached.

This message has been here for ages and either people ignore it because
they are so used to using -aux or never see it. It was here before 2005
and really 7 years is enought time to people to change their ways.
The notice is now removed, people who make usenames like "x" deserve all
the punishment they can get.

Strings with lower caps & no trailing dots have greater change to
have multiple occurences, meaning less effort for translators, than
strings with them.

The catastrophic_failure function tries to make bug reporting useful
by telling in which line error occured, and drops core.

This commit represents an experiment in nls help text support.
The word --help itself been made translatable along with the
help section names and their abbreviations. Thus, the work of
the translators will ultimately alter program run-time behavior.
Perhaps someday all "long" options can behave in a similar way
which could offer a considerable benefit to other languages.
Instead of translationg just option descriptions, the long
forms of those options could also be transalated.
This commit also:
. includes the section abbreviations in --help output
. isolates all --help support in the ps/help.c module
. provides (hopefully) meaningful Translator guidance
. removes --help support from the ps/common.h header
. removes --help support from the ps/parser.c module
. eliminates tabs in line with the style of other ps modules
. eliminates the need for the include/c.h header file
This commit is prmarily concerned with elimnating deugging only
code from the nls template file.
It also eliminates any remaing useless trailing whitespace.
This patch mostly reorganizes include files and eliminates
some useless trailing whitespace.
It also adopts the standard procps-ng unconditional approach
to nls initialization.
These xalloc functions are a private function for the library. If using
programs need them, then they should make their own error reporting or
use a common file.
Slackware seems to have this patch, while it is not in use(?) Well,
the upstream procps-ng allows one to disable warnings if that is
wanted. After all having this sort of 'feature' does not cost much,
while lacking it might annoy someone.
A patch from Slackware.

There were numerous ps memory allocation inconsistencies.
Some were checked for failure and others were not.
The program was modified to utilize the library memory
rouines which are consistent in dealing with errors.
