[Python-projects] Flag missing else: clauses?

[skip at pobox.com]

Can I get pylint to flag missing else clauses in if statements?  For example
(snippet from daemonize.sf.net which just reminded me I wanted to ask this
awhile ago):

    process_id = os.fork()
    if process_id < 0:
        sys.exit(1)
    elif process_id != 0:
        sys.exit(0)
    # This is the child process.  Continue.

This is perfectly fine code, but I run into code all the time where the
missing else: clause is a bug.

    process_id = os.fork()
    if process_id < 0:
        sys.exit(1)
    elif process_id != 0:
        sys.exit(0)
    else:
        # This is the child process.  Continue.
        pass

Thanks,
