I have no strong opinion, I proposed this patch because of your request. 
But C-u RET is better I think, it's a single command instead of two (C-r 
RET and C-s RET).  For the two other commands, I don't know an easy way to 
mark the match.

Yes, I was proposing something more general, with what I understood from 
the discussion.

> But IMO the C-u C-u C-u is not the way we should go..

I think it's easy to type, much easier than M-s RET for example, but as I 
sait I have no strong opinion on this, it's fine if my patch isn't 
applied.
