Yes, your macro is the same as mine, except that you do not include these 3
bindings (you use them only in `isearch-edit-string'):

 (message-log-max           nil)
 (history-add-new-input     nil)
 (minibuffer-history-symbol nil)

And you do not update `isearch-new-string' and `isearch-new-message' in the
macro itself, but outside it (in the macro callers).

Your tweak improves the macro - my vote says go for it.

I suggest changing the name slightly: `with-isearch-suspended' (or perhaps just
`isearch-suspend').
