[O] [BUG] [Babel] Do not try to process inline source in macro templates

[Nicolas Girard]

When a buffer contains such

    #+MACRO: m src_emacs-lisp[:results raw]{(do-something "$1")}

macro template, calling =org-babel-execute-buffer= using =C-c C-v C-b= yields

    if: No id found: $1

It seems to me that Babel shouldn't be looking for inline code within
macro templates.

Cheers,
