Add work-around for VA_ARGS_NARGS() on MSVC.

The previous coding of VA_ARGS_NARGS() always returned 1 on Visual
Studio, because it treats __VA_ARGS__ as a single token unless you jump
through extra hoops.  Newer compilers have an option to fix that.  Add a
comment about that so that we can remember to clean this up in the
future when our minimum MSVC version advances.
