Hi Gregory:

Maybe I am wrong but I think it makes no sense to add C-u RET for this;
because it is not better than C-r RET. Same applies to the other two
commands.

I am only interested in the first one really; and for that case I would
prefer something shorter like M-RET and for the others maybe C-M-@ (just
to mention random examples that are shorter, free or "similar" somehow
to what happens outside isearch). We can consider things like M-s RET;
M-@ and so on too... But IMO the C-u C-u C-u is not the way we should
go..

Does it makes sense?

Ergus?
