Feature Request: Show all errors per file, instead of just first

[TedGardner]

When using Betterer to incrementally update a large project, it can take a long time to run through the tests. Only showing the first error encountered in a file isn't very helpful because it requires re-running Betterer each time an error is fixed, which can be a very time consuming process.

Please allow a configuration option to show all results, instead of just the first result.

Does betterer results not do what you want? https://phenomnomnominal.github.io/betterer/docs/results-summary

[TedGardner]

I mean new errors, not old ones reported by the results command. When you get more than one per file, the errors are listed under a bit that says “Showing first of N new issues”. It would be more convenient to show all of them if it takes too long to run the tests.
