command line history broken in 11.0

[Ernie Luzar]

On 10.3 I had the current session saving the command line history when 
issuing the shutdown, halt, and reboot command by using these alias 
commands that I added to the .cshrc file of my logged in user account.

alias sd	"exit && shutdown now"
alias sdp	"exit && shutdown -p now"
alias rboot     "exit && reboot"
alias stop      "exit && halt"

Now after doing a clean install of 11.0 and using the same .cshrc file 
the rboot and stop alias commands no longer save the current history. 
They act like the exit command is not getting executed. The sd and sdp 
alias commands are working as expected.

When existing from a session terminal by issuing the exit command does 
still save the current history.

Is there an alternate method I can use?

Here is my .cshrc file

  alias sd	"exit && shutdown now"
  alias sdp	"exit && shutdown -p now"
  alias rboot    "exit && reboot"
  alias stop     "exit && halt"
