[O] [ANN] Incompatible change in (eval ...) macros

[Nicolas Goaziou]

Hello,

This is a heads-up about a small incompatible change in (eval ...)
macros. Here is the related ORG-NEWS entry:

    Within =(eval ...)= macros, =$1=-like placeholders are always replaced
    with a string.  As a consequence, they must not be enclosed within
    quotes. As an illustration, consider the following, now valid,
    examples:

    #+begin_example
      ,#+macro: join (eval (concat $1 $2))
      ,#+macro: sum (eval (+ (string-to-number $1) (string-to-number $2)))

      {{{join(a,b)}}} => ab
      {{{sum(1,2)}}}  => 3
    #+end_example

    However, there is no change in non-eval macros:

    #+begin_example
      ,#+macro: disp argument: $1

      {{{disp(text)}}} => argument: text
    #+end_example


This is necessary to fix an issue when the arguments of the macro
contain special characters (e.g., \ and ").
