----------------------------------------

Hi Jarcec,
I have one user experience suggestion on your approach. After performing help 
with command and function, a user has to type same command again or erase 
"help" at the start by moving cursor while using history. 

With given patch : Help argument at end of whole command, using command history 
then user will erase only last help argument alone without moving cursor.
