Hmm, that's not the behavior I see, even in emacs -Q. Regardless of whether it's `t' or `lazy', the first TAB press completes any common prefix, and then the very next TAB press shows the completions buffer. I never get the "Next char is not unique" message (I checked the Messages buffer to be sure). I don't have time to dig deeper into this right now, but I'll come back to it, probably on Monday.
