aa3348db86 top: restore ending ']' when summary graphs are scaled
When a visual separator was added to 2 abreast summary
items in a recent commit, this bug was introduced. So,
from that earlier patch we'll revert one line of code.

The bug surfaced under an 80/even column terminal only
when that '4' toggle was off. With an an 81/odd column
screen, it existed in both single and 2 abreast modes.

[ this commit also goes the extra distance to ensure ]
[ two abreast mode maximizes available screen width. ]

d7e6c27a79 top: ensure those potential focused tasks stay focused
When that 'F' focus command has been applied to a task
in forest view it should remain as the topmost process
in a particular window. But without this patch that is
not guaranteed. Newly forked/cloned tasks 'above' such
a process result in task(s) appearing which shouldn't.

The effect was as if that up arrow key scrolled beyond
the topmost parent task, which would never be allowed.

[ since scrolling is permitted within a focus range, ]
[ when any task 'above' our focus/topmost task ends, ]
[ we respond as if scrolled with the down arrow key. ]

[ that result is completely appropriate. if the user ]
[ wishes to return to a focused parent, the up arrow ]
[ or home key can be used to accomplish such a goal. ]

systemd-sysctl handles glob patterns along with overrides and

271004bd0d top: some minor tweaks supporting long cmdline options
This darn patch began as 1 correction to an extraneous
comma in the man document. Then, it grew to include an
adjustment for a couple of additional man page things.

After that, I figured I might as well tighten up logic
dealing with those awful gaps in the getopt_long code.

[ will only be taken when '=' ends the argv vectors! ]

016ddc6bff top: utilize getopt and introduce long cmdline options
For quite some time now, top has stood out like a sore
thumb regarding the approach to cmdline options & help
text.  Only short options were used and that same help
text was displayed for '-h' (help) plus 'v' (version).

[ also, top 'rolled his own' when it came to parsing ]
[ options while avoiding that getopt implementation. ]

Well, with this commit all of that has changed and top
now has added a long form of his options. Additionally
he employs getopt_long() for the bulk of that parsing.

[ however, top will still avoid separate fputs calls ]
[ characteristic of other procps-ng programs when it ]
[ comes to help. rather all such text is one string. ]

Along the way, the following major getopt deficiencies
were addressed, assuming the absence of a new #define:

* an equals sign ('=') is allowed on both option forms

* whitespace is allowed before & after the equals sign

* optional arguments needn't abut their related option
for short form nor is an '=' required with either form

c725207c44 top: add a visual separator to lines printed 2 abreast
When the '4' toggle is on, and Summary Area %Cpu lines
are shown two abreast, it's not always clear where the
separation is between the two processors. So with this
patch we'll now print a vertical bar separator between
them (looking similar to the existing field headings).

We will also reduce that 'GRAPH_suffix' constant to 1,
reflecting the the trailing ']' bracket only, so as to
maximize top's exploitation of available screen width.

bdd50fa2fc top: introduced new focus toggle ('F'), program source
Sometimes, it might be useful to isolate a parent task
and its forked children from other system activity. As
an example, a user might want to examine workload in a
specific lxc container. Or maybe there is some need to
question what's happening under the same tmux session.

Since forest view mode tends to be a relatively stable
display, it will sometimes satisfy the above need. But
that mode can't currently guarantee the target process
always remains as the topmost task or even is visible.

So, this patch will enable focusing on any parent task
and keeping it as the topmost process while displaying
it and its forked children only. It then appears as if
there is no other activity in that system by virtue of
the blank lines which follow that final child process.

To implement this new feature, top's redundant 'F' key
has been repurposed. It made little sense devoting two
keys to the Fields Management screen (especially since
the key we've taken required two separate keystrokes).

[ and while we're at it, i also added punctuation to ]
[ that prologue for 'forest_display' since all other ]
[ forest functions used punctuation. And, instead of ]
[ a pointer to a proc_t he will now get a ppt index. ]

dc8137f85b top: refactor 'mkVIZ' support to avoid future problems
In the patch referenced below, 2 potential abends were
fixed both of which involved 'alternate display mode'.

The root cause of those abends was a negative value in
the 'begnext' field for other than the current window.

And while that potential is fixed for now the existing
code almost invites such problems again in the future.

So, this patch will remove any temptation to name some
other window in the 'mkVIZrow1' macro. And, since that
macro is not the only source of 'begnext' changes, the
'mkVizrowX' is being added to identify such occasions.

[ and for symmetry i've added a 'mkVIZyes' macro and ]
[ ameliorated an otherwise surreptitious assignment! ]

84e85611c3 top: fix two potential 'alternate display mode' abends
This commit will address potential abends upon leaving
the windows help or color mapping screens and invoking
alternate display mode ('A').  It only happens if that
current window was changed with multiple 'a'/'w' keys.

So now, rather than leaving a trail of negative values
in the 'begtask' field, compliments of that win_select
function, we'll remove the mkVIZrow1 macro. Henceforth
it will be issued just once per user interaction. Thus
a promise of 'Curwin' only being impacted is restored.
