Behavior change with 20041231 snapshot


I've noticed a slight change in behavior from 1.5.12 and the 20041231 
snapshot. It's affecting my scripts, but I'm not sure whether the old or 
new behavior is correct.

The command

  % bash --login -c 'sleep 10 &'

used to return immediately. Now, it waits until the child process 
(sleep) completes.

I've also noticed that

  % bash -c 'sleep 10 &'

does return immediately. I've tried removing my .profile and .bashrc 
files to see if that made a difference, but it doesn't.

The command

  % bash --login -c 'setsid sleep 10 &'

does return immediately.
