Should a dissector that uses "proto_tree_add_item()" to add an
FT_STRINGZ item find out how many bytes the NUL-terminated string takes
(including the NUL, if any), so that it can advance an offset variable,
by using "proto_item_get_len()" after adding the item?

(Note that the protocol tree tvbuff cursor stuff in "ptvcursor.c" can do
this for you; a ptvcursor has a pointer to a protocol tree, a pointer to
a tvbuff, and an offset, and "ptvcursor_add()" adds an item, whose data
is at the current offset in the ptvcursor and whose length, byte order,
and field handle are specified in the call, to the protocol tree, and
advances the offset for you.)
