The default is `ask`, which is documented to mean:

    If `ask', prompt when patterns found in buffer; if bound to a
    function,

but `(describe-function 'progn)` doesn't describe any patterns.

(FWIW, I'm very much not a fan of this default.  If the user didn't want
them highlighted, she would not have turned on `global-hi-lock-mode`.)
