• Added .editorconfig for basic cross-editor configuration for generic files

ENDRELEASENOTES

Editorconfig is a popular tool for portable configuration of editors. It's automatically recognized by some editors (vim, neovim, github editor) or has a plugin for the others (emacs, vscode, clion, sublime). The tool takes lower precedence than any language specific config so there shouldn't be conflicts

Here I propose a very basic config that will automatically add newline at the end of any file so hopefully there will be less small corrections like in #660 (comment)

I'm not this will help a lot. In my opinion configuration should be done on the user side, then formatting should be automatic and done in CI; ideally we never need to run clang-format and other tools.

So precisely because it's a plugin for the most used editor it's very likely it wouldn't have done anything since it's not installed by default? Some flags are supported in some plugins some are not on different plugins...

I would not like adding it for similar reasons.

[m-fila]

Yes, but it's meant as some minimal sane config that might be applied if not then anyway

There is a little chance that the plugin will be there (since once installed it'll be there an you can forget about it) or the editor might suggest it. The most used editor will not pop-up a suggestion for this but the extension should appear in recommended based on the files present

[m-fila]

ok, closing

I'm not opposed to adding it, I just don't think it's going to be very useful for people that make those mistakes

[tmadlener]

I think it could be useful given the VSCode support and that that is what many people nowadays use. For those it would take care of a few otherwise annoying things. The rest probably has their editor configured in some other way in any case, so for them it doesn't do any harm either.
