bug#15275: 24.3; replace-string function does not respect current region

[Jarek Czekalski]

emacs started with -Q. Documentation of function (replace-string)
says:

In Transient Mark mode, if the mark is active, operate on the contents
of the region.  Otherwise, operate from point to the end of the buffer.

However I can't make it work on a region and it always replaces
from the point up to the end of buffer. For example this call:

(replace-string "a" "x")

If I execute it through M-x, it works correctly, working only on the region.

1. Mark a region
2. Replace string

      M-x replace-string RET a RET x RET

3. Do 

     M-x list-command-histort RET

4. You will find something like this.

    (replace-string "a" "x" nil
                    (if (and transient-mark-mode mark-active)
                        (region-beginning))
                    (if (and transient-mark-mode mark-active)
                        (region-end)))

This will probably provide some clue on what you are looking for.

bug#15275: 24.3; replace-string function does not respect current region

[Glenn Morris]

In non-interactive use, you need to specify START and END explicitly.
This is fairly common for Emacs commands.
But note that the doc-string says: "This function is usually the wrong
thing to use in a Lisp program."

I was not going to use it from Lisp program. I just find it convenient 
to have the whole replacement command on one line. If the function 
worked the way it is described in docs, it would be perfect.

But I am emacs newbie, you decide. A newbie just reads the docs and 
hopes the program works according to docs.
