Details:

The parse_cmdlineoptions() function enforces an ordering in the options that
isn't clear from the documentation. Generally speaking, options
(--compare-hash) should be allowed in any order and only required arguments
([source destination], [statfile1 statfile2 ...], etc) should need to have an
ordering enforced.

Python's OptParse was released in Python 2.3 and exists up until 2.7. It's
deprecated for argparse, which is available in Python 2.7 and Python 3+.

I suspect we don't want to require Python 2.7, but we can probably stomach
dropping support for Python 2.2 and prior.

Expected Behaviour:
$ rdiff-backup backup/ -l
increments.2011-08-23T12:00:04-05:00.dir   Tue Aug 23 12:00:04 2011
increments.2011-08-24T12:00:05-05:00.dir   Wed Aug 24 12:00:05 2011
increments.2011-08-24T14:47:58-05:00.dir   Wed Aug 24 14:47:58 2011
Current mirror: Wed Aug 24 17:19:17 2011
$ rdiff-backup -l backup/
increments.2011-08-23T12:00:04-05:00.dir   Tue Aug 23 12:00:04 2011
increments.2011-08-24T12:00:05-05:00.dir   Wed Aug 24 12:00:05 2011
increments.2011-08-24T14:47:58-05:00.dir   Wed Aug 24 14:47:58 2011
Current mirror: Wed Aug 24 17:19:17 2011

Observed Behaviour
$ rdiff-backup backup/ -l
Fatal Error: File server-bak does not look like an increment file.
Try restoring from an increment file (the filenames look like
"foobar.2001-09-01T04:49:04-07:00.diff").
