Re: [PATCH v3 1/9] bugreport: add tool to generate debugging info

> Teach Git how to prompt the user for a good bug report: reproduction
> steps, expected behavior, and actual behavior. Later, Git can learn how
> to collect some diagnostic information from the repository.
> 
> If users can send us a well-written bug report which contains diagnostic
> information we would otherwise need to ask the user for, we can reduce
> the number of question-and-answer round trips between the reporter and
> the Git contributor.
> 
> Users may also wish to send a report like this to their local "Git
> expert" if they have put their repository into a state they are confused
> by.
