Indenting space is not removed from indented code blocks

[pbb72]

When writing code blocks by indenting the lines with a space, this indenting space should not be included in the output.

Wiki code:

 require 'rubygems'
 require 'rake'
 require File.join(File.dirname(__FILE__),'init')

Mediawiki output:

<pre>require 'rubygems'
require 'rake'
require File.join(File.dirname(__FILE__),'init')
</pre>

Wikicloth output:

<pre> require 'rubygems'
 require 'rake'
 require File.join(File.dirname(__FILE__),'init')
</pre>

(Note the extra spaces at the beginning of each line in the Wikicloth HTML output.)
