nargs.REMAINDER not eating all args

[Michael Edwards]

I have some argparse code included below. In it I try to eat a --browsers with nargs=* and a --remote-url string arg. Both are optional. Anything else should be passed on to another application using argparse.REMAINDER. However, if I execute 'app --param-meant-for-lettuce blah' then my argparser complains instead of passing it on to the other app. Most other use cases appear to work fine (ie 'app somebarparamforotherapp' executes fine). Am I doing something wrong or is this an argparse defect? According to the documentation this should work. I'm executing this under Python 2.6 and 2.7.
