Thank you, Juri

Perhaps we could store in a defvar the last message echoed by
repeat-mode to make easier this check?

Today I caught a small problem with the patch I sent. The
'string-prefix-p' and 'string-match-p' handle nil inputs differently:

(string-prefix-p "Repeat with " nil) ;; returns nil
(string-match-p "Repeat with " nil)  ;; throws an error

The problem can be reproduced by writing some elisp code in *scratch*
buffer, putting the cursor in the function definition and invoking the
'other-window' with 'repeat-mode' using my original steps. The
'eldoc-mode' will echo the function name and '(current-message)' will
return nil.

A simple patch:
