Displaying commands called with prefix argument

[yantar92]

It is not currently possible to distinguish between commands called with and without prefix arguments (numeric or C-u). Yet, this information is important to understand what is happening - command behaviour might be significantly changed depending on the prefix argument.

It would be nice to display the non-nil prefix argument in addition to the nominal key sequence.

I have noticed that too. It looks like `C-u` is displayed as separate command. So actually you can see that it was pressed. But yea, I would like to have it the same way it is shown in echo area.
