standards.7: Correct various details in the explanation of XPG/POSIX/SUS

As reported by mail from Geoff Clare, there are some details that
need correcting:

Subject: standards(7) (was: man-pages-5.07 released)
Date: Wed, 10 Jun 2020 10:53:14 +0100
From: Geoff Clare <gwc@opengroup.org>

...

The first isn't really a problem, just an oddity. You list
POSIX.1b as "formerly known as POSIX.4", but you don't do the
equivalent for POSIX.1c ("formerly known as POSIX.4a").

There are several problems with the XPG3 entry:

    "first significant release" - although I suppose XPG3 could
    be considered more significant than XPG2 because it was the
    first one to incorporate POSIX.1, I don't think it's fair to
    imply that XPG2 was not significant.  (E.g. XPG2 was
    significant in that it was the first release to include
    I18N, and the first that had a conformance test suite.)

    "produced by the X/Open Company, a multivendor consortium" -
    this conflates two different things called X/Open. X/Open
    Company Limited is the UK company that did the editing work,
    organised meetings, etc. X/Open Group is the consortium
    whose members developed the technical content.

    "This multivolume guide was based on the POSIX standards" -
    at the time there was only one POSIX standard, namely
    POSIX.1-1988.  The first release to incorporate POSIX.2 was
    XPG4 (which you may consider worth noting in the XPG4
    entry).

To fix these problems I would suggest changing the entry to:

XPG3  Released in 1989, this was the first release of the X/Open
      Portability Guide to be based on a POSIX standard
      (POSIX.1-1988).  This multivolume guide was developed by the
      X/Open Group, a multivendor consortium.

Under SUSv2 I would suggest changing:

    Sometimes also referred to as XPG5.

to:

    Sometimes also referred to (incorrectly) as XPG5.

Under POSIX.1-2001, SUSv3: "XSI conformance constitutes the Single
UNIX Specification version 3 (SUSv3)" is problematic.  I think I
touched on this in the previous discussion. I would suggest
deleting that sentence and instead inserting, before "Two
Technical Corrigenda ...", the following:

    The Single UNIX Specification version 3 (SUSv3) comprises the
    Base Specifications containing XBD, XSH, XCU and XRAT as
    above, plus X/Open Curses Issue 4 version 2 as an extra volume
    that is not in POSIX.1-2001.

Something similar is needed in the POSIX.1-2008, SUSv4 entry where
it talks about "the same four parts". The extra volume this time
is X/Open Curses Issue 7.

However, the plan was always to eventually remove them, after

atoi.3: Explain disadvantages of atoi()

I believe new users should be discouraged from using atoi() and
that its disadvantages should be explained.

I added the information that 0 is returned on error - although C
standard and POSIX say that "If the value of the result cannot be
represented, the behavior is undefined." there are some
interpretations that 0 has to be returned
https://stackoverflow.com/questions/38393162/what-can-i-assume-about-the-behaviour-of-atoi-on-error
and this is also what happens in practice with glibc, musl and
uClibc.

proc.5: Inform that comm in /proc/pid/{stat,status} might also be truncated

pgrep for example searches for a process name in /proc/pid/status
and therefore cannot find processes whose names are longer than 15
characters unless -f is specified.

setns.2: Document the use of PID file descriptors with setns()

Starting with Linux 5.8, setns() can take a PID file descriptor as
an argument, and move the caller into or more of the namespaces of
the thread referred to by that descriptor.

setns.2: It is possible to setns() to the caller's current PID namespace

The page currently incorrectly says that 'fd' must refer to
a descendant PID namespace. However, 'fd' can also refer to
the caller's current PID namespace. Verified by experiment,
and also comments in kernel/pid_namespace.c (Linux 5.8-rc1).
