It makes sense, but it would also be desirable to make it customizable.

To some extent I can see that it is slightly different in the Isearch
context.  I'm not sure if it is sufficiently different to justify
changing the default in Isearch, but I'm not necessarily opposed to
it either.

IOW, I agree with both feature requests.

Yes, that's a bug.
