Might be nice to see if the plugin dev wants to add the plugin to G-P and help them with it, or at least reference it from the "third party" section of the plugins pages.
Yeah, but it shouldn't block this PR. All it does is add some boilerplate file to make Geany's code look OK on Github. Nowhere in the tarball release or installed program does it have to mention `.editorconfig`, confusing users.
