GitHub's web interface already supports editorconfig files which is handy when viewing diffs for code which use an other than 4-space tab setting. This formatting definition file is supported by a lot of apps and platforms already, you can see a complete list on this page:
http://editorconfig.org/
The problem I'm facing is that when viewing diffs in SourceTree for a project that uses tabs with an 8-space width, nothing is lined up correctly. On GitHub the diff is viewable without a problem (because it reads an editorconfig file when present). And in my editor (Visual Studio Code) everything is lined up correctly because I'm using an editorconfig plugin.
