Yes, I meen exactly this.
Also, current implementation follows this strategy - accroding to the tests,
and according to it's source code.

So it is strange for me, that the standard for num_get<>::do_get() say, that
only string() is indicator of no grouping at all.
While string(1,-1) and string(1,CHAR_MAX) also force number representation to
have only one group.
