Looks good! Thanks for the patch. We'll need a maintainer to review though.

@w0rp tests have been written and documentation added. Can we reopen this and get it merged?

@Hnasar @w0rp can we add this functionality?

@w0rp @Hnasar after using vim-lsp as a standalone for a few years, I'm coming back to using ALE precisely because the error messaging in vim-lsp in diff buffers caused odd jumping around the file. I hadn't realized this was never merged because I had it locally, but if I'm coming back because vim-lsp is insufficient for diff buffers then it doesn't really make sense if it's not supported. Can we reopen and merge this?

Am I missing something here? I don't want to obnoxiously bump, but I also don't want it to get stale.

Another gentle bump
