In release 3.3.6, some commands were equipped with the
concept of a 'default pid'. The initial implementation
meant that the intuitive <Esc> key would not always be
treated as one would expect under any well behaved UI.
This patch ensures the expected <Esc> key behavior of:
terminating user input while still making possible the
necessary distinction between 'no input' & 'defaults'.

The majority of changes in this commit are intended to
enable translation of top's man page. There were three
kinds of errors as seen by that po4a-updatepo program.
. a valid but unrecognized request concerning no-break
. an internally defined macro with a groff .de request
. occasional apostrophe at the beginning of some lines
With respect to the apostrophe, some have been changed
to back-tic since line placement could not be assured.
And other parts were re-flowed to avoid temptations to
escape as \' (technically an acute accent). Of course,
the opening back-tic with closing apostrophe looks odd
when ASCII, but should be rendered correctly as UTF-8.
It may yet be necessary to change the remaining single
'opening' quotes to back-tics as translation proceeds.
Should that become necessary, I intend to reduce quote
usage to the bare minimum throughout the man document.
There were also some formatting changes to enhance the
man2html output and then to other formats via htmldoc.
And, I wish to acknowledge that my meager groff skills
do not serve those programs very well at all. In other
words groff yet remains mostly incomprehensible to me.
Lastly a few content plus copyright updates were made.
Message(s):
. Unknown macro '.c2 `'. Remove it from the document, or refer to the Locale::Po4a::Man manpage to see how po4a can handle new macros.

Confession is supposed to be good for the sole, right?
After a senior moment regarding the 'x' toggle quirks,
and thinking top had somehow regressed, I concluded an
additional explanatory note might well be appropriate.
Those quirks were already documented under the 5d & 5e
topics. But there was no such caution documented under
the 'x' command explanation itself, found in topic 4c.

After revisiting the issue of a new field, combining 2
existing fields (RES and SWAP), I've decided it indeed
makes sense. After all, with the vastly expanded field
capability and the ease of adding new fields, it would
save some precious horizontal screen real estate while
also eliminating some mental/manual user calculations.

This commit corrects one reference to 'decimal place'.
Even though a running top supports a delay interval of
unlimited precision, and a delay interval of thousands
of a second in the rcfile, we intentionally imply that
any delay interval is limited to tenths of a sec only.
Later in the man document, in section 7a, one finds an
admission that a user can set any desired delay value.

There existed a small chance that the display could be
corrupted when a search string was found within a row.
For that to happen, conditions like these were needed:
. a very short Locate string was active in some window
. the string matched part of a terminfo <esc> sequence
. that sequence was used in highlighting running tasks
. the 'x' toggle was active (sort column highlighting)
One solution to this potential problem was to manually
turn off sort column highlighting before using Locate.
But rather than rely on a user remedy, we'll automate.
Since other top provisions were already being enforced
when Locate was in use (off 'i' and/or 'u'/'U'), we'll
now also force column highlighting off when the search
string in a given window is not empty. However, unlike
idle tasks and user filtering, when that search string
*is* emptied, we restore highlighting for that window.

In a effort to anticipate a potential future wishlist,
the recent '-o' sort override command line switch will
now support an override of the sort direction as well.
By prepending a '+' or '-' to any valid field name the
user will be able to guarantee a specific desired sort
direction. The '+' forces a high-to-low (normal) order
while a '-' reverses that to yield a low-to-high sort.
Without this addition users would be left to the mercy
of whatever was last specified for Curwin as reflected
in the rcfile or top's default of a high-to-low order.

The recent change to task area memory scaling was just
a little short of optimum in its consistency and upper
limits. In fact, top could only scale memory fields up
to a maximum of 99.9999 TiB (with VIRT a little more).
While that seems like more than enough it was actually
artificially low, due to an unnecessary decimal place.
So, this commit standardizes both precision and widths
to achieve a minimum amount of scaling beyond the user
requested target plus reclaim some horizontal spacing.
. VIRT & DATA are now 7 bytes wide (not eight and six)
. other memory fields are 6 wide (were formerly seven)
. as before, KiB shows whole numbers only (no decimal)
. MiB, for its precision, shows a single decimal place
. all other memory ranges display three decimal places
The net result is a more homogeneous display with less
forced scaling and the recovery of three lost columns.

Everyone has either accepted this potential distortion
or patched top to eliminate it. Now, the time has come
to regain some consistency when calculating that %CPU.
We'll now limit such values to: 100.0 * total threads.
And, it took way too long to address this little flaw.

With the increased width and precision of memory and %
columns, the proliferation of 0's when there's nothing
to report seems like a distraction versus useful data.
This commit introduces the '0' toggle which can either
display or suppress those zeros. And, like the scaling
states this new state is also preserved in the rcfile.

This commit is an unrequested outgrowth of the earlier
change dealing with summary area memory field scaling.
That user selectable scaling provision is now extended
to include 6 (at present) task oriented memory fields.
The new companion 'e' (lower case) interactive command
has been added and, like the 'E' command, it can cycle
each of the currently displayed memory columns between
KiB through TiB. There are, however, some differences.
Where '+' indicates summary area truncation at a given
radix, task memory fields are automatically scaled for
their column. Thus, not all rows use the same scaling.
And, while summary area field widths were not changed,
the task memory columns were widened in order to offer
more meaningful data when the radix was increased. The
precision is automatically increased in step with each
radix: MiB displays 2 decimal places, GiB 3 and TiB 4.
To compliment that additional precision, both the %CPU
and %MEM fields were widened by 1 column and now offer
precision up to 3 decimal places. But, unique to %CPU,
widening could already have occurred due to the number
of processors in some massively parallel boxes. At any
rate, total extra width for both memory and percentage
fields could amount to twenty (precious) columns more.
So for both the memory and % fields the original width
(along with loss of precision) can be restored via new
compiler conditionals which this commit also provides.
p.s. and it will be rcfile preserved for any restarts!

Earlier this year, the switch from KiB to Mib as shown
in top's summary area was postponed to those occasions
when KiB exceeded 8 digits. In hindsight that may have
moved top in the wrong direction, given the difficulty
of digesting such large numbers of digits at a glance.
This commit adds a new 'E' interactive command used to
cycle the displayed memory amounts ranging from KiB to
TiB. Thus, users can choose the radix they wish shown.

This 'Sleeping in function' field was made variable
width because the length of current kernel symbols
usually exceeded the former top's 9 character limit.
As a variable width field it would steal valuable
horizontal display positions from other, more likely,
displayed fields such as COMMAND or CGROUPS.
With the advent of the new 'X' toggle, no fixed-width
non-scalable field need suffer permanent truncation.
Thus, WCHAN is being made fixed width with a default
size of 10 characters.
