Hi, this is a feature request and if people would like it then I will submit a pull request.

What I would like is to be able to specify in the config an output file on a per hook basis. When the hook is run, it will output to that file (as well as to STDOUT as currently).

The reason I want this is because I want to run pre-commit on Jenkins and I want the reports of certain tools to be stored in files so that they can be easily consumed by Jenkins.
