PATCH: Complete with _arguments -- for zsh

[Mikael Magnusson <mikachu@xxxxxxxxx>]

I sort of threw options at _arguments until it worked like I wanted,
Frank tested it too and it seems to work fine. The only thing it doesn't
do is complete the -o option itself more than one time, but it didn't
complete it at all before so I consider it an improvement still.
