From a24b5dbd2dc91b6fc3088c77a946fd8931e7e7dd Mon Sep 17 00:00:00 2001
From: Ludovic Court`es
Date: Fri, 8 Dec 2006 08:19:12 +0000
Subject: lout & latex engines: Fixed the output of `&prog-line'.

* src/guile/skribilo/engine/latex.scm: Use `(srfi srfi-13)'.
  (&prog-line): Use markup option `:number' instead of `markup-ident' as
  the line number.

* src/guile/skribilo/engine/lout.scm: Likewise.
