all: further adjustments for new Ronna, Quetta SI prefixes

* src/dd.c (parse_integer): Support Q,R suffixes.
* src/od.c (main): Likewise.
* src/split.c (main): Likewise.
* src/stdbuf.c (parse_size): Likewise.
* src/truncate.c (main): Likewise.
* src/sort.c (specify_size_size): Likewise.
Also line length syntax check fix.
* tests/misc/numfmt.pl: Adust top end large number checks
to the new largest values.
* doc/coreutils.texi (numfmt invocation): Add a numfmt example.
* NEWS: Tweak to aid searchability.

 ** Changes in behavior
 
-  Programs now use the new SI prefixes R (10**27) and Q (10**30)
-  along with their binary counterparts Ri (2**90) and Qi (2**100).
+  Programs now support the new Ronna (R), and Quetta (Q) SI prefixes,
+  corresponding to 10^27 and 10^30 respectively,
+  along with their binary counterparts Ri (2^90) and Qi (2^100).
   In some cases (e.g., 'sort -h') these new prefixes simply work;
   in others, where they exceed integer width limits, they now elicit
   the same integer overflow diagnostics as other large prefixes.
