From: Oleksandr Andrushchenko <oleksandr_andrushche...@epam.com>
There are range sets which should not be printed, so introduce a flag
which allows marking those as such. Implement relevant logic to skip
such entries while printing.
While at it also simplify the definition of the flags by directly
defining those without helpers.
