No longer able to send blank lines in multi-session mode via Commands interface

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Open two (or more) Putty windows, configure them in split screen mode to 
allow commands to be sent to both.
2. Send a test command to show that commands are in fact being sent to both 
windows.
3. Press enter, or click the green check mark, while in the Commands field, and 
nothing (nor any blank line) will be sent.

What is the expected output? What do you see instead?
There should be a blank line sent to each terminal in the split-screen mode 
when enter by itself or the green check is pressed.  What happens?  Nothing, 
unfortunately.

What version of the product are you using? On what operating system?
This issue was introduced in version 1.4.0.4, and is not present in 1.4.0.3.  
Running on Windows XP, Vista, 7, etc.

Please provide any additional information below.

Suggestion:  Revert the behavior for handling enter/blank lines to the previous 
behavior (sending blank lines to each session), and provide a configuration 
option that will allow users to disable sending blank lines if they do not wish 
to do so.
