1. emacs -Q

2. Ensure that `isearch-allow-prefix' is non-nil, which it is by default.

3. Search for anything, such as character `e', then hit `C-u C-u':

 C-s e C-u C-u

The second `C-u' terminates Isearch.  It should not.  The raw prefix arg
`(16)' should be passed through to whatever command is invoked by the
next key sequence.

The second `C-u' acts as if `isearch-allow-prefix' were nil.

Note that in Emacs 23, if `isearch-allow-scroll' is non-nil then `C-u
C-u' is passed through OK.  (In Emacs 23, `isearch-allow-prefix' does
not exist.)

But in Emacs 24.4 and later even the workaround of setting
`isearch-allow-scroll' to `t' does not work, to correct the
prefix-arg problem.  The second `C-u' always exits Isearch.

So this is a regression wrt that workaround.  The regression was introduced in Emacs 24.4, which is also when `isearch-allow-prefix'
was introduced.
