encoding/gob: clarify docs about pointers to zero values not being sent

The documentation on encoding/gob mentions that pointers are flattened,
and it also explicitly says that empty values are not sent.

A corollary of this, is that pointers to zero values are not sent, i.e.,
gob-encoding of *false becomes nil on the receiver side.

It is worth documenting this explicitly.
