Oh, just had a thought about moving the first line: @baronfel that would break the VS Code problem matcher, wouldn't it?

Oof, you're right. We'd need to check and update those

I checked the matcher regex and it doesn't (for example) support all combinations we have for line/column info. For example case when lineNumber != 0 && columnNumber == 0 && endLineNumber != 0.

As discussed offline, we will not wait for VSCode update.

@MichalPavlik the diff is now showing 277 modified files. Something didn't go well with rebase/merge.

I had to rebase to register this feature. I'm not sure what happened, but these additional changes should reflect current main.

I reconstructed commit stream on top of main, but it looks like I'm removing Jakub's changes for some reason....
