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