Then I submit that we don't need the uncalled-for "Multi" in the
prompt.

That information confuses when the user didn't ask for this to happen.

It is OK to show "Multi" when the user explicitly invokes
multi-isearch.

It should be documented earlier, right where I-Search is first
introduced, because from the user perspective, she just invoked a
simple I-Search.
