From 5617d303ebb53291567f5b8199afb2d95db8e89b Mon Sep 17 00:00:00 2001
From: Ludovic Court`es
Date: Mon, 4 Jun 2007 12:43:42 +0000
Subject: Fixed handling of figure numbering in `ref'.

* src/guile/skribilo/ast.scm (markup-number-string): Don't use a
  hierarchical numbering scheme for figures.

* src/guile/skribilo/engine/lout.scm (ref): Use `markup-number-string'
  rather than `@NumberOf' to determine the number of a figure.  This
  guarantees numbering consistency.
