Bug Report -- replace-regexp-in-string from subr.el

[Sam Fiechter]

Hi,

I noticed that the lisp function replace-regexp-in-string from emacs 24.4.50.1 does not pass the sub-_expression_ match when the rep is a function call rather than a string.  

For Example:

(progn

  (defun samscat (s)

      (concat "[" s "]"))

 (replace-regexp-in-string "\\(foo\\).*\\'" 'samscat " foo foo" nil nil 1))

returns:

" [foo foo] foo"

 not:

" [foo] foo"

looking at the code, I notice that the sub-_expression_ is hard-coded on line 3642 of subr.el.gz:

    (funcall rep (match-string 0 str)))

rather than:

     (funcall rep (match-string (or subexp 0) str)))

I hope this is helpful!  

Here's my about emacs screen:

This is GNU Emacs, one component of the GNU/Linux operating system.

GNU Emacs 24.4.50.1 (i686-pc-linux-gnu, GTK+ Version 2.24.10)
