Thanks for spotting this outdated bit in the documentation. Updated now
in R-devel. The byte-code compiler does additional optimizations - the
contexts are not included when not needed, and source
references/expressions are tracked in a different way. That is
documented in the compiler documentation.

Be something like:
Note that whilst calls to closures always set a context,
those to builtins only set a context under profiling
or if they are of the foreign variety (e.g `.C` and similar),
and those to special internal functions never do.
Based on the 'eval.c' source[2].
