[Rd] source definition for R_NilValue/return from TYPEOF(R_NilValue)

[Gábor Csárdi]

It is in the source:
https://github.com/wch/r-source/blob/ea8c13aef93058c71d647619583b561567856584/src/include/Rinternals.h#L110
https://github.com/wch/r-source/blob/ea8c13aef93058c71d647619583b561567856584/src/include/Rinternals.h#L1798

It could probably be in
https://cran.r-project.org/doc/manuals/r-devel/R-lang.html#NULL-object
