From d70f8ef391dd4a71ad26bbf76c6f33b0f7b47390 Mon Sep 17 00:00:00 2001
From: Ludovic Court`es
Date: Thu, 12 Oct 2006 16:01:47 +0000
Subject: prog: Fixed line number output (`&prog-line').

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

* src/guile/skribilo/prog.scm: Use `%skribilo-module-reader'.
  (make-prog-body): Pass the line number as a `:number' markup option in
  the `&prog-line' markup.
