Thanks, but the doc string of the new function is hard to understand:

> +(defvar replace-regexp-function nil
> +  "Function to convert a search string to a regexp to replace.
> +It's bound to `isearch-regexp-function' when searching
> +for a string to replace.")

The first sentence is unclear: what do you mean by "convert a search
string to a regexp to replace"?  What "search string" is being
converted to regexp, and how does "replace" enter this picture?

And this:

  It's bound to `isearch-regexp-function' when searching

seems to be incorrect: it's isearch-regexp-function that's bound to
replace-regexp-function, not the other way around.

Can you clarify the doc string, please?
