This program was well equipped to properly handle utf8
multi-byte characters - except for one important area!
If users typed any unicode character (shift+ctrl+u) or
pasted a utf-8 multi-byte string as a response to some
input prompt, those characters would simply be ignored
since they would not pass the internal 'isprint' test.
Well, now we can handle such data while preserving all
line editing provisions such as insertions, deletions,
destructive backspace, prior line recall (up/down) and
those all important cursor left plus right arrow keys.

In the commit shown below the bottom window was forced
off if a full screen replacement function was invoked.
It did so by setting Frames_signal after calling those
routines from the keys_global function. However, there
was sometimes a possibility such action was premature.
At least two of those full screen replacement routines
may issue an error message & return without corrupting
the screen. As such, forcing off that bottom window is
totally unnecessary. It therefore should be preserved.
So this commit just moves the setting of Frames_signal
to the full screen replacement routines when possible.

In the patch referenced below the bottom 'Ctrl' window
was made to remain until it was dismissed by the user.
As such, it required abandoning a 'Cap_nl_clreos' used
when all the terminal rows had not been drawn. Instead
each line had to be cleared individually until the row
reserved for that 'Ctrl' window area had been reached.
Unfortunately, while a 'Cap_nl_clreos' didn't create a
problem for 'batch' mode, a 'Cap_clr_eol' used instead
yielded an unending loop if those rows were limitless.
So, now we will only clear that area when top isn't in
'batch' mode (which should have always been the case).

Well darn it, whoever wrote that new library caught me
with my pants down (again?). Shoot, they were not just
down but somehow missing altogether. Here's the story.
Any item from that library supported by dynamic memory
can only be represented in user's stacks exactly once.
Should any string based enumerator be duplicated among
the items array, for any instance beyond the first the
library will return '[ duplicate ENUM ]' for a result.
That's where I lost my pants. While command lines were
given special handling (and never duplicated) I failed
to turn on CGROUPS, SUPGRPS & ENVIRON when testing the
Ctrl-G, Ctrl-U & Ctrl-N keys. If any of those 3 are on
that's when a Ctrl window sees a 'duplicate' notation.

top: added fields for 'start time' & 'cpu utilization'
This patch will exploit some new library capabilities.
[ one will raise eyebrows, the other likely will not ]
A new 'STARTED' field was added which shows the time a
process started after system boot. As such the largest
interval represents the most recently started process.
This is the field that will likely be questioned since
it's somewhat counterintuitive. But were we to instead
use TIME_ELAPSED, the value will change with every top
refresh. This will defeat any PUFF macro optimization.
The new '%CUU' field will probably be better received.
It represents the cpu usage over the life of the task.
When a process was showing high %CPU usage, this field
can be used to determine if it's an anomaly or normal.
[ and as with %CPU, %CUU shows a '?' when running in ]
[ a namespace when /proc was mounted with subset=pid ]
---------------------------------- newlib patch #2 ---
top: tweaked the recently introduced 'STARTED' support
When the 'STARTED' field was added, the width was made
the same as the 'TIME+' field. Thus, a full time could
be shown (which then included hundredths of a second).
That kind of granularity is totally unnecessary. After
all, this column is potentially confusing enough since
it is so counterintuitive. So, this commit will reduce
the width of the field with some help from scale_tics.
Henceforth it will not include those ol' centiseconds.

---------------------------------- newlib patch #1 ---
top: refactor 'scale_tics' function for better scaling
This patch refactors the 'scale_tics' function to more
closely parallel uptime shown on the first line of the
summary area. The old logic has been preserved through
the header file's new #define SCALE_FORMER provision.
However, the former logic was actually a big disaster.
These are some potential problems with that old logic:
1. With respect to our time fields top no longer deals
solely with cpu time. So, the old limits of '68 weeks'
could possibly be insufficient to reflect those times.
2. Given the widths of top's new time fields, the code
never got beyond scaling to hours. For example, with a
ridiculously large span of 19 years, the scaled result
would then be shown as '167832h'. We never reached the
days ('6993d') or even the weeks ('999w') equivalents.
3. Similarly, with that 'TIME+' field and a large tics
value, results would then appear as 'MMMMMM:SS' rather
than the more meaningful 'HH:MM:SS' or days and hours.
So henceforth we will adopt these scaling conventions:
MMM:SS.hh ... minutes:seconds.hundredths
MMM:SS ...... minutes:seconds
HH,MM ....... hours,minutes
D+H ......... days+hours (with 'd' & 'h' suffixes)
D ........... days (with 'd' suffix)
W+D ......... weeks+days (with 'w' & 'd' suffixes)
W ........... weeks (with 'w' suffix)
Note that, unlike our former scaling logic, that 'MMM'
portion won't be allowed to grow unconditionally. It's
limited (arbitrarily?) to 360 total minutes (6 hours).
Additionally, the 'HH' guy will be limited to 96 hours
(4 days) while that 'D' limit was set at 14 (2 weeks).
Whenever a limit is hit, scaling will advance a level.
---------------------------------- newlib patch #2 ---
top: extended 'scale_tics' function for Ctrl-E scaling
That normalization of the 'scale_tics' function in the
prior commit convinced me that I won't please everyone
with my arbitrary choices for the scaling transitions.
So, this patch will provide the users with a means for
setting their own scaling transition points with a new
toggle. Ctrl-E was chosen since the 'e/E' toggles were
already present as a means of scaling (albeit memory).
[ this toggle will also serve an educational purpose ]
[ by allowing one to see all the scaling conventions ]
The scaling a user establishes is saved in the rcfile.
---------------------------------- newlib patch #3 ---
top: enhanced 'scale_tics' function for Ctrl-E scaling
When scale_tics was refactored and then Ctrl-E support
added to top, the complete range of scaling values was

was never seen with ^E. With this commit they will be.

In the patch referenced below the focus task logic was
improved to ensure that newly cloned tasks 'above' the
focused task did not force an effect like the up arrow
key. That commit also acknowledged that when some task
'above' ended, it *would* act like the down arrow key.
Well, with this commit a task ending 'above' a focused
task no longer distorts the focus. That's assuming the
new '#define FOCUS_HARD_Y' is specified plus the total
focused tasks does not exceed the current screen rows.
Thus, the manual scrolling with up and down arrow keys
is allowed when the total focused exceeds screen rows.
