Sorry if that was unclear: I think we'd need to update the docstring of 
fileloop-initialize-replace. Which doesn't offer any hints that the 
logic of isearch-no-upper-case-p will be employed.

Also see the part about obeying the value of search-upper-case.

Since we bind search-upper-case to nil in this patch, perform-replace 
won't try to alter the value of case-fold-search internally.
