Difference in RE between 3.2 and 3.3 (or Aaron Swartz memorial)

[Matej Cepl]

Hi,

as my method to commemorate Aaron Swartz, I have decided to port his 
html2text to work fully with the latest python 3.3. After some time 
dealing with various bugs, I have now in my repo 
https://github.com/mcepl/html2text (branch python3) working solution 
which works all the way to python 3.2 (inclusive; 
https://travis-ci.org/mcepl/html2text). However, the last problem 
remains. This

<li>Run this command:
<pre>ls -l *.html</pre></li>
<li>?</li>

should lead to

  * Run this command: 
    
        ls -l *.html

  * ?

but it doesn’t. It leads to this (with python 3.3 only)

    * Run this command: 
          ls -l *.html
  
    * ?

Does anybody know about something which changed in modules re or 
html.parser between 3.2 and 3.3, which could influence this script?

Thanks,

Matěj Cepl
