Details:

When running a multi-line selection in the editor, only the last line is
really executed. Example: 

Runing the selection


a = 1
b = 2
c = 3


from the editor leads to the result in the console window


>> a = 1

c =  3
>> b = 2


Only c = 3 is executed, a and b are still undefined afterwards. The previous
commands for a and b were only written into the command line and probably were
replaced by the following command before execution. Therefore, b = 2 is
restored after c = 3 has been executed. 

jwe, could this be a regression from changeset 420611c61298 (eliminating the
cmd-classes)? I remember that I have implemented the extra queue of cmd
objects in the gui because of similar issues, i.e., dropping command requests
from the gui in case of several commands in a sequence.
