This PR is an experiment in ergonomics of
flake8
output with the--isort-show-traceback
option.At the moment the full traceback is printed with each message emitted. When I'm running flake8 on the command line this leads to very verbose output.
This PR changes that behaviour so that the traceback is printed only once with the last message of the file.
Feel free to throw this away if you prefer the existing behaviour; while this change is nicer for me I can imagine there are situations where repeating the traceback with every message might be desirable.
