On a related note, other bottom-level things act strangely:

> sys.parent()
Error: failed to match environments
> sys.nframe()
Error: failed to match environments
> sys.frame(0)
Error: failed to match environments

The 1st might make sense (I'd prefer it to return NULL whenever n is
bigger than the stack height, rather than error out), but the 2nd
should return 0 and the 3rd the R_GlobalEnv as it does on any other
levels.
