FWIW, with Isearch+ you can search or query-replace multiple regions
(which can be defined in several ways, including just by their limits),
including across multiple buffers.

But I'm glad that you're adding this to isearch.el and also providing
rectangle search, even if it means additional Isearch+ work. ;-)
