Clarify the choice of rscale in numeric_sqrt().

Improve the comment explaining the choice of rscale in numeric_sqrt(),
and ensure that the code works consistently when other values of
NBASE/DEC_DIGITS are used.

Note that, in practice, we always expect DEC_DIGITS == 4, and this
does not change the computation in that case.

Joel Jacobson and Dean Rasheed
