Re: [PATCH v5 3/7] completion: bisect: complete custom terms and related options

> git bisect supports the use of custom terms via the --term-(new|bad) and
> --term-(old|good) options, but the completion code doesn't know about
> these options or the new subcommands they define.
> 
> Add support for these options and the custom subcommands by checking for
> BISECT_TERMS and adding them to the list of subcommands.  Add tests.
