The previous version of sysctl had the form:
sysctl -p [file]
In other words, it required a space between the -p and the [file].
Omitting the space would lead to an error.
The new version though is the opposite:
sysctl -p[file]
In other words, it requires there to not be a space.
Considering the old behavior has been around for a decade, and runtime
checking for this mismatch in behavior is silly, and supporting the old
syntax is trivial, add support for it.
When '-p regexp' is glob is used to make reqular expression to be
expanded to argument list, which also means that -p option will
allow multiple files being specified as input.

There's an off-by-one error in the count (".conf" is 5 bytes, not 6),
and the logic is inverted for the strcmp return value -- we want to
skip the files when they *don't* end in .conf, not when they *do*.
Also fix the off-by-one len check.

The library does not weed out potential duplicate PID
values when sampling with the PROC_PID flag. This was
treated as merely an inefficiency by top and safely
ignored prior to the advent of forest view mode.
Now, however, if the -p switch duplicates certain PIDs,
*and* those processes have no PPID, *and* top's forest
view mode is active or activated, then a SEGV will be
generated (and caught).
This rather obscure buglet is thus limited to pid #1
(/sbin/init) and pid #2 (kthreadd). With any other
duplicate PIDs the worse case scenario was a '?' in
place of the usual forest view artwork.
This commit silently ignores any duplicate process ids
and thereby avoids the potential segmemtation fault.

The problem is that in ./proc/sysinfo.c uptime(), it is not
considered that the "savelocale" string is overwritten by the
subsequent call to setlocale(). Hence restoring the locale later on
won't work this way. "savelocale" ought to be a copy of the string
pointed to by setlocale()'s return-value.

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,

Since there were already other conditions where no

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.

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.
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.
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.

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:
