Thanks for you answer.

Well the procedure is complete: C-f moves the point until you reach the 
end of the message and then it changes the prompt. If you do C-e as I 
explained before C-f, the point should already be at the end of the 
message and therefore it can't move further.

I tried to add a slash, the problem is the same, as demonstrated in the 
attached gif.
