Aren't we over-engineering this stuff?  IMNSHO, separate histories
could be just fine, since it's easy enough to change the Isearch mode
after you have the previous search string in the minibuffer.  And if
you remember your previous searches, you most probably also remember
whether you searched for a string as a symbol or a word or whatever.

By contrast, breaking back-compatibility for this reason sounds gross
to me.
