Since C-u is always a prefix character, would it make sense to you for
it not to quit isearch if the character that follows a C-u opt/number
prefix is a key sequence that is currently in use by isearch, and for it
to quit Isearch and pass the prefix on to the non-isearch command

In this case, `C-u C-n' would exit isearch and move down 4 lines, whereas
`C-u n' would add four "n"s to the current search string.
