0 - Reload in 5 on CLI

S8_Test_CPE#reload in 5
Reload scheduled for 15:30:08 DST Sat Apr 11 2015 (in 5 minutes) by deploy on vty1 (10.171.0.22)
Reload reason: Reload Command
Proceed with reload? [confirm]

Explained:

All the newlines in this are output by the router, ter mon is off.

This is the direct output, using openssh, of issuing reload in 5. The prompt follows the confirm, then the shutdown in 5 is output.

S8_Test_CPE#reload in 5
Reload scheduled for 09:29:51 DST Sun Apr 12 2015 (in 5 minutes) by johnf on vty0 (10.171.0.22)
Reload reason: Reload Command
Proceed with reload? [confirm]
S8_Test_CPE#


***
*** --- SHUTDOWN in 0:05:00 ---
***

I now press enter a few times for a fresh prompt, then issue reload cancel. The same behaviour is observed; reload cancel immediately returns a prompt, then the shutdown aborted text is output. 

S8_Test_CPE#reload cancel
S8_Test_CPE#


***
*** --- SHUTDOWN ABORTED ---
***

It looks like two leading new lines, followed by the message, then one trailing newline. No new prompt is issued after the output.
