Inline question on ctor+nullptr

----------------
I'm working from the paper at https://isocpp.org/files/papers/N3762.html, and I
find it a little sketchy on the policy for nullptrs.
Since the ctor above accepts nullptr as long as the length is zero, would it
make sense to do that here too? That is, only call _Traits::length for
non-nullptr __s args?
