Allow multiple paths as argument

[mrjoops]

User story.
As a CI tool, I can lint all the files in a repository, so that I can see a report for all the files with a single command line.

Is your feature request related to a problem?
It is time consuming to iterate manually through all files, run the command, store the status, do some computation to get the global status and display the report.

Describe the solution you'd like
Today only one file is accepted as argument, it would be great to accept multiple paths (file or directory), maybe with wildcards too.

@mrjoops
Thank you for submitting the idea. I really like it.
It's in fact something we could improve, therefore I'm more than happy to include it in our development roadmap.
I can't promise on any deliverables in this or next week, but hopefully the change is included in the next major or minor release.

I put it into the October feature sprint so that'll probably be v5.1 as this feature sprint aims to get v5.0-beta1 ready.
