Agreed.  It will also show up when you hit M-% or similarly reuse the
last search string in things like occur.  It can all be fixed with more
code, but it complicates everything for very little benefit.
I'd rather we just don't bother with search-whitespace-regexp in the
default isearch behavior, especially since nobody actually requested
it, AFAICT (at best, people pointed out that it seems counterintuitive
to have it in regexp-search but not in the normal search).
