So far Stephen was concerned with the expanding step only.  But any
difference between `grow-only' and t should have an impact iff the
height of the minibuffer changes from some value `old' to some value
`new' where 1 < new < old.  IIUC `eldoc-mode' never shrinks the echo
area back to some value > 1.
