About the feature, I'm not sure if everyone will like it like this. Maybe add an opt-in flag to format the errors before the report has finished? (like it was before, but now is opt-in). Or maybe don't add a flag now, and maybe add the opt-in flag later if we receive complaints?

It's possible for anyone to write their own reporter to make it look exactly how they want. There are already a number of reporters available on npm, and one potentially in the works for node core. We also don't make semver guarantees about exact reporter formatting.

Can you update the tests so that this doesn't get stalled out.

ping @Llorx. Are you still working on this? If not, can we close this PR out? I'd like to see this issue get resolved.
