Did Zechariah predict the coming of Jesus?
One will say to him, 'What are these wounds between your hands?' Then he will answer, 'Those with which I was wounded in the house of my friends. Zechariah 13:6
It has nothing to to with the hands in the sense that they pretend was due to the Romans. In fact, Rashi says that the context is speaking about false prophets (verse 2). If it were talking about Jesus it would be calling him a false prophet. As we see in Rashi on 13:2
And also the prophets: The false prophets.
And one will say to him, "What are these wounds between your hands?" And he shall say, "That I was smitten in the house of my friends."
And one will say to him, “What are these wounds between your hands?”: Between your shoulders. There they flog the sinners.

In the context of your question, Zechariah is speaking of what will happen after the mashiach comes and the House of David restored. In that time, the false prophets will be ashamed of what they have done and the lies that they have told. They will deny have prophesied at all (much less falsely) and say that the marks of punishment are not punishment for having prophesied falsely, but for other sins.
Thus, even though oso haish was a false prophet (according to his followers), he is still not referenced here as that time still had many false prophets who refused to admit their errors.
