Done. Pre-processed the ifs, then used a giant string with format, similar to header()

Kept it as-is for now as I'm not a fan of using regexps when not absolutely necessary :)

No good reason apparently, dropped.

Done.

Done

Done

Done

Right, at first read, I assumed that restrictions_list could be None, but rechecking the code, that's not actually the case, so iterating will always work and that if statement is unnecessary. Dropped.

Agreed, done.

I'd rather not depend on python 3.3. Some people may still want to use the fixed script on something slightly older, but that's good to know nevertheless.

> * line 430: extra parens

Fixed that one and another one a few lines further down.

As far as I can tell, the script still works with those changes and the output is similar.
