Now we are always using the same text also for commands
which had still hardcoded descriptions or where we can't
use the standard print_usage_help_options macro.

* assume ncursesw headers in ncursesw/ directory only
* prefer long paths, <term.h> and <ncurses.h> should be last
possibility
* fix typos

text-utils/tailf.c:69:21: warning: Using plain integer as NULL pointer
Since many 'struct option' has used zero as NULL make them more readable in
same go by reindenting, and using named argument requirements.

Mainly: showing that the word color is a placeholder by writing
<color>, showing some numbers as optional, and message levels
and colors as not optional.

Commit 3393c136 caused regression. The klogctl() logging range is 1-8,
but the value 0 is special according to setterm.1 manual page. It turns
on loging, same way as '-msg on' option.

It is enough trouble to keep usage output aligned with getopt() parsing,
manual page, and bash-completion, so get rid of the unnecessary effort
duplication.

Earlier the function was in the middle of option parsing code segment,
and screendump() required function prototype.

Check the input numbers are numbers, which makes also the code shorter,
and user experience better as half invalid imputs will error.

While the -version style options will work for next unknown number of
years start moving towards user interface that has way of invoking long
options as most of the other commands.

The getopt_long_only() has advantage of allowing one and two hyphen
versions of options, for example -help and --help. Secondly the getopt
function family from libc can ensure some options requiring arguments,
while other are optional, and some should not accept argument at all.
That makes option parsing more robust.
Unfortunately retiring the old option parsing makes this change greater
than preferred. Assuming not mistakes happen the new code works
functionally exactly as the old did.

The ncurses term.h header has logic in it to detect if nucrses.h has
already been included and void defining things when it has. But since
setterm includes term.h and the ncurses.h, it doesn't work and we can
get fun build-time warnings like:
CC term-utils/setterm-setterm.o
