Also save wrong commands in the terminal history

[TimJ0212]

During my work on #208 I noticed that wrong commands are not stored in the history of the terminal. If you look at the behavior of a "real" console, you realize that this should be the case though. Especially in case of a typo, it's nice to just get to the last command and fix the error there.
After a look at the code, this would be done very quickly. Feel free to assign this to me, PR would come quickly.
