Silviu Baranga efaef1bba2 Don't overread or write memory returned by _DTOA_R 
Don't over-read memory returned by _DTOA_R, and never write to it
since the result might be a string literal.

For example, when doing:
  swprintf(tt, 20, L"%.*f", 6, 0.0);

we will get back "0".

Instead, write the result returned by _DTOA_R to the output buffer.
After this, write the 0 chars directly to the the output buffer
(if there are any). This also has the (marginal) advantage that
we read/write less memory overall.
