Thanks.

Consider adding a repeat-mode-echo option which follows what Smartrep 
does: instead of adding to the echo area, it just highlights the changed 
state in the mode line (basically a long mode lighter saying 
"========SMARTREP=======") and also colors the mode-line green.

IME that works well as an indicator that we're in a "special" state.

Though perhaps we could use a smaller text (like "[REPEAT]") and only 
color the text inside the brackets, rather than the whole mode-line. 
Could use some experimentation.
