do nothing when editor-config is activated

I agree that if editorconfig is active then dtrt-indent should defer to it, but otherwise, it should work as normal: if the user doesn't want to use editorconfig, then dtrt-indent should do its job, and also it's not really dtrt-indent's place to notify the user about editorconfig (they may neither know nor care about it).

It's easy enough to detect whether editorconfig is installed and active, but how to detect whether there is a configuration for the current project? It seems to me that by dtrt-indent's philosophy, which is that it tries to guess the right thing to do, it should remain active if editorconfig is not run. It seems that editorconfig runs before the major mode hooks (it hooks into change-major-mode-after-body-hook, which runs before the major mode hooks (where dtrt-indent-mode is run), but editorconfig-apply doesn't seem to set anything to say that it has run. (I'm also not sure whether dtrt-indent should run when editorconfig-apply has run but unsuccessfully—probably not.)

How about if dtrt-indent-mode simply ignore any settings that already have a buffer-local override? That should make it leave alone any relevant settings applied by editorconfig and also other packages, such as prettier. I suppose it would be a fairly major change at this point but I can't see how it would hurt.

@jscheid That seems reasonable.
