Better debugging mail server

Python includes (and Django recommends) a simple email debugging server which prints mail to stdout. The trouble is, unlike any half-competent mail reader, long lines are broken up, and thus long URLs don't work without modification.

This snippet simply unwraps long lines (broken by "=") so long URLs can be easily copied/pasted from the terminal.

Save this snippet into a file named "better.py" and execute it.
