fix(dotenv): draw confirmation prompt in next empty line

Browse source 
Without this fix the confirmation prompt appears wherever the cursor is,
which means that it might appear in the command line when using a widget
that changes the directory without redrawing the prompt (an example of
this are the dircycle and dirhistory plugins).
