Maybe there was a misunderstanding here: I didn't mean <prefix> to be
a prefix argument only for the following command. I meant it to be a
command to switch "grabbing" on/off (for the entire Isearch session).

I definitively misunderstood you.

Your proposal is basically what I had in my mind, but always with
"grabbing" switched on.

In that case I like it, but I would make a small adjustment: Let's
suppose that you are in forward Isearch mode and have grabbed a couple
of words after the point. Then you change your mind and want to grab
only the first word. In that case, would be convenient to allow M-b
without exiting Isearch mode.

Thus, I propose two alternatives:
a) In Isearch (forward or backward), every movement command would
update the grabbed text. If the last grabbed text was in a different
side of the point than current, switch the direction of the Isearch.
b) The same, but replacing the direction switching with "exit Isearch
mode and move point in the buffer".
