Describe Request:

I would like to see what files were matched and checked by shellcheck in addition to whether or not the check was successful.

Examples:

For example I just added shellcheck to this project heroku/buildpacks-ruby#33. I want it to check shellcheck -x bin/build bin/compile bin/detect bin/release bin/support/bash_functions.sh but i'm unsure if it found all those files or not.

If this can be accomplished without a feature, please let me know.
