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.

e9a9bad264 top: document an existing provision of pid monitoring
Since its inception top has provided for monitoring
only specific process ids via the -p command line
switch.  This provision has also embraced the top
process itself, even though its pid wasn't yet known.

This commit simply documents the special zero value,
which would otherwise be an invalid process id.

cd253e0dc6 top: fix a segfault when -p switch specified invalid pid
In attempting to keep at least one task visible when
scrolling vertically, a negative task index would be
produced when pid monitoring was in effect and no
matching pid was found.

Since there were already other conditions where no
task might displayed, the faulty source line has been
removed.

fa21a6ca81 top: correct loss of keystrokes paste capability
When top introduced true line input editing, the
ability to paste keystrokes was lost.  This remains
a necessary evil so that top has an opportunity to
translate cursor motion keystrokes into terminfo
escapes during line input.  Motion keys themselves,
of course, can never be pasted.

If pasting ever became more important than input
editing, then native termios support should have been
available via a define called TERMIOS_ONLY.  But a
recent commit, eliminating what was thought to be
obsolete logic, rendered the alternate linein()
function virtually useless.

Similar to top-3.2.8, when native termios input is
functional, these abberations can be experienced:
. cursor motion keys will appear as escapes
. excessive input can cause line wraps
. ^Z during i/p is not be honored until <Enter>
. SIGWINCH during i/p corrupts screen temporarily

In hindsight, it now seems that the ability to paste
keystrokes may indeed outweigh any shortcomings of
native termios support.  This is especially true if
one is preparing to search ('L') for some lengthy
process command line contined in the clipboard.

Thus, this patch fixes the alternate linein() function
and changes TERMIOS_ONLY to TERMIO_PROXY so that top
now defaults to using native termios input.  In turn,
that will restore the paste keystrokes capability.

ddfc402886 Don't check if output changed on first screen.
When invoked with the --chgexit/-g options wait until we have at
least one screen of output before checking if the output changed.
Otherwise, we're comparing the initial screen of output to all
spaces, which usually isn't what we want.

f5a3afdcae watch: exit cleanly when falling through main loop.
Revert commit ffe5e0b08e.  Restores
clean exit when falling through main loop.

Previously, watch only exited when there was an error or when
interrupted by the user.  Commit 81f64657ba
added another exit condition when the watched command's output
changes, causing execution to fall out of the main loop.

With this change, watch correctly restores the terminal and returns
an exit code indicating success when invoked with the --chgexit/-g
options.

2fc3f15770 top: refer to memory using strict IEC standard names
Admittedly, top referred to memory quantities in
a variety of non-standard ways.  This commit brings
the program and supporting documentation into strict
compliance with IEC standard binary names.

According to wikipedia, as of 2012 this IEC standard
was still not in widespread use.  However, I'm making
this change now for the anal-retentive among us.

87bb21b557 top: fix selected miscellaneous compiler warnings
These per instance warnings have been eliminated:
warning: range expressions in switch statements are non-standard
warning: padding struct to align 'winflags'
warning: dereferencing type-punned pointer will break strict-aliasing rules

   These per instance warnings have not been addressed
   since they simply trade one warning for another:
      From:
warning: ISO C does not permit named variadic macros
warning: ISO C does not support the '%Lu' gnu_scanf format
      To:
warning: anonymous variadic macros were introduced in C99
warning: ISO C90 does not support the 'll' gnu_scanf length modifier

   Lastly, since all C compilers have supported use of
   C++ style comments for the past 20 years, the top
   program will never trade them for the often more
   cumbersome C style comments simply to avoid this
   once per source file warning:
warning: C++ style comments are not allowed in ISO C90
