Respect .editorconfig settings
Created by: adrianblynch
Not to be a github-do-it-so-you-should-too request, but respecting a .editorconfig file would mean being able to set tab widths when viewing code.
It would mean tabs going from the default width of 8:

To a more reasonable 4:

Or what ever the .editorconfig is set to. Your code, your choice!
