Gets the number of values that are part of the set from first to last
(inclusive).
Note that this function returns a vte.types.TEST_FLAGS_NONE, because when all values are
set, the return value is G_MAXUINT + 1. Unless you are sure this cannot
happen (it can't with gio.list_model.ListModel), be sure to use a 64bit type.
