@steffhip found that while the translation hint said use 9 characters in
the free headers, it really was only 7.
Currently each line is constructed with the following (in non wide format):
Header + 6 Columns. The header takes 7 characters and each column is 11
characters wide and prefixed with one space. Thus we have
7 + (1 + 11) * 6 = 79 characters for each line
By dropping the leading space for the first column after the header -the
header is already terminated by a colon- one could indeed provide the needed
9 letters for the header and thus have 9 + 11 * 1 + (1 + 11) * 5 = 80 Chars
per line which would fit into one line.
Well, shit! With release 4.0 on March 25th the lxc/lxd
folks have stuck it to us once again. They changed the
cgroup lxc prefix used to identify the container name.

Reimplementation of pidof for procps toolset contains sort of deactivated code and does not return results for processes without task.cmdline entry (usually kernel worker threads). Old pidof and pgrep do that in comparison. Despite all perks provided by using pgrep instead, pidof should show those workers again.
Several years after the 'e' & 'E' interactive commands
were introduce to affect memory scaling, an 'E' switch
was added. This was after discovering a dropped Redhat
patch which provided a unique 'M' command line switch.
If only for symmetry it makes sense to offer a similar
command switch ('e') for the Task Area memory scaling.
As was true with 'E', top's help text will show 'e' as
if it were a switch without arguments in order to keep
help text displayed without wrap in an 80x24 terminal.
The man page, however, will show all of the arguments.

The Debian bug referenced below has nothing to do with
locales. In fact, top was made locale independent back
in release 3.3.13 (April, 2018). However, that bug did
reveal some misplaced logic which this patch corrects.
Prompted by the Qualys audit, all rcfile field strings
were checked for potential duplicates which could only
have resulted from some user's manual/malicious edits.
Unfortunately, that code was executed before top had a
chance to enforce the proper/maximum string length (in
the event an extremely old rcfile had just been read).
This created some potential string overrun references.
In top's original 3.3.15 implementation, the potential
overrun extended for 15 characters. That is the number
of field characters added with 3.3.9 (December, 2013).
But, since strchr() was used, no error exit was taken.
In the revised 3.3.16 implementation, the strchr() was
replaced with '&w->rc.fieldscur[n]'. This held overrun
to a single position while producing an error message.
So, this commit just moves that logic to a point where
fieldscur is guaranteed to be longer than EU_MAXPFLGS.

When that potential abend at program end was addressed
in the patch shown below, one line of code was removed
in error. That line served to suppress some end-of-job
reports should ATEOJ_RPTSTD or ATEOJ_RPTHSH be active.
So, this patch restores that previously deleted logic.

Unfortunately, that disabled the associated core dump.
This patch restores expected behavior of those signals

there was one intervening 'item' to which that caution

This commit duplicates a change to that newlib branch.
However, it should be noted that such a change was not
really necessary under this master branch since proc_t
data remains valid much longer. It is being duplicated
here as documentation only. Below is the original msg.
------------------------------------------------------
This patch will eliminate a bug which is unique to our
newlib branch. It's extremely rare and only happens if
a search ('L'/'&') is initiated during the period when
fields are currently being auto-sized (AUTOX_MODE on).
This bug surfaces as either all zero results for tasks
displayed or a segmentation fault, depending upon what
fields were activated. It is caused by the timing of a
call to the <pids> 'reset' function. When called after
a task refresh, but before do_key(), this bug appears.
So this patch just ensures that 'reset' will be called
after do_key() & before the tasks have been refreshed.

Previous release incremented the age instead of incrementing the
revision. The age can only increment if revision (internal changes
only) or current (API changes) also increments.
A C:R:A of 8.0.2 means its the latest revision of 8.0 library and
any binary linked against 8.0 will work. This is our third revision
of the 8.0 library.

The install target was using the wrong directory and would throw
some errors where a language couldn't translate man pages. This
one should be hopefully more robust.
Downloaded the updated translations of the binaries and the manpages
from translation project. Then fixed the typos that caused po4a to
fail, mainly errant spaces.
Using the newer po4a tool for manpage translations. Also removing
the manpage po file update from dist target because it should be
something the is explicitly done.
The git repository will hold the original man pages and the
po translation files. The distribution tarball will hold those
and the translated manpages. This means most people won't need po4a
as the distribution fill will have these translated manpages.
The previous Makefile rule would only put the first required file
into the pot file because it used $< Unfortunately, due to how
po4a tools work, its not just a simple matter of changing it to $^
and you're done, but needs a foreach loop to add -m to each manpage
file.
This is a temporary fix, after some more work looking into po4a the
unified tool (called po4a) will be used.
Beyond the copyrights, the single oops in the man page
was introduced in the commit which is referenced below
dealing with some cleanup following that Qualys audit.

@MarsChan correctly pointed out that the read() always returns 128
bytes, so skipping on >= 128 will always mean we skip. Their suggestion
was to remove the equality, but read will never go past 128 bytes so
I just removed that part of the check.

Short separator option used 's' instead of 'S' which
meant it pidof would use the single-shot option when you
meant separator.
Added alias for -S using -d to give some sysvinit pidof

The backtrace shown in the bug report referenced below
illustrates a 'normal' program termination interrupted
with some signal, ultimately then causing a top crash.
So this commit just rearranges a little code such that
all signals will be blocked during that rather lengthy
end of program processing regardless of how initiated.
[ in that report, ignore the assertion regarding the ]
[ '-n' option. it obviously was not '1' since do_key ]
[ had been called, which otherwise wouldn't be true. ]
[ and when it is '1' the -d option would be ignored. ]

This commit most significant change is the elimination
of the kbd_ENTER entry from that tinfo_tab in iokey().
That entry was a useless artifact left from the commit
which is shown below. It makes no sense to 'translate'
a keystroke into something it already was (i.e. '\n').
The remaining changes just reorder those table entries
for a progression consistent with vim keys: h,j,k & l.
