Version 2.0 has a known X86 issue: if you disassemble a buffer of instructions
that having the first byte as a prefix (LOCK, REP, REPNE), and you only
get 1 instruction (passing 1 as value for the 'count' argument), then only
the prefix will be returned as instruction.

An work-around is to disassemble the whole buffer & get out the first
instruction, then this instruction would properly include both prefix and
the next instruction.

This issue will be fixed in the next version.
