Well, this isn't the most robust and someone will probably say not to
use regular expressions, but the Q&D way is:

import re
fixed = re.sub(r'(http:[^\s\n\r]+)', r'<a href="\1">\1</a>',
your_string)

NB. If the URLs are malformed (like have spaces in them, or are broken
over several lines) this won't work right.
