/assist question

[gaeorn]

Its been so long since I played on live, I'm not sure I remember accurately how /assist worked on live. I know that when you /assist a mob or player that has a target, you got their target. But what happened when you /assist a mob or player that does not have a target? Currently, the emu sets the target to yourself. This can be misleading since I have more than once thought, "now why does that mob have me targeted?"

What I can't remember is when you /assist someone who doesn't have a target, does your target get cleared or does it just stay with the same target you had before the /assist command? I'd like to create patches to correct this, but I need to know what the proper behavior is before I do.
