It also means that size is not decremented, for example when + * a ModR/M byte is used.

Weird, yes, confusing, yes, welcome + * to the Intel ISA. Another note: tbl_prefix is used as an override, so an + * empty insn in a prefix table causes the instruction in the original table + * to be used, rather than an invalid insn being generated. + *
