snoozing a task of type 'next' causes the next step to show up

Yes, this would indeed be a bug. However, it doesn't seem to happen in the current trunk. I tried with this file:

; TKDO: depth=3
[_] blah
 ; TKDO: T=next
 [Z] one
  ; TKDO: Z=2009-09-21@21:41+1d
 [_] two
 [_] three

I also tried with a "D=+6m" attached to "blah", and it still appears to work.

So, I'm filing this here in case the issue comes back later, or to attach details of which exact versions have the bug.
