No, I can just launch ‘emacs -Q’, go to the beginning of the buffer
and start searching for something with ‘C-s M-s '’ to get the
flickering prompt. What the settings in the first message do is change
the prompt: it is ‘Pending char-fold I-search’ without them (after
doing ‘C-s M-s '’) and just ‘I-search:’ with them (where just ‘C-s’
suffices for starting a char-folded search).

Your patch works both with and without my settings. I don’t know if
there are cases where it suppresses useful messages.
