Document meaning of Version, SpacesAftertabs, and PassedFiles keys in config file

[krzysztof-sikorski]

Command ec -init generates a sample configuration file, and most of its content is described somewhere in documentation, but three of the keys are not documented: Version, SpacesAftertabs, and PassedFiles.

I had to search source code to (partially) guess what these options do, and I am still not sure if I understood Go code correctly:

• the Version field seems to be used for some kind of version compatibility check (to not allow using old config file after installing a different version of the tool?)
• the SpacesAftertabs flag seems to be used to allow using mixed tabs-and-spaces indentation
• ... and I have completely no idea what PassedFiles option means

It would be nice if documentation was updated (both in README and on editorconfig-checker.github.io page) to mention these options and describe what they do.

Hey you are very right.
It would be amazing if you could send a PR to document these values.

@mstruebing the problem is understanding what these options mean.

I never learnt Go and I can only guess what the source code does based on my general knowledge of other programming languages, and I am not sure if I guessed correctly.

If one of the devs (or other people that understand the code better than me) could confirm or summarise what these options do, then yes, I would gladly do the chore of making a patch or PR that updates the docs.
