@vlsi That is an interesting suggestion. My experience with `.editorconfig` is that it is a bit so-so about getting it to actually describe the coding practices of a project, but it can probably be used for a thing like stripping trailing whitespace.

I suggest we continue that discussion in ide-support-dev at openjdk.org, to figure out exactly what can be added to an `.editorconfig file`, how it interacts with jcheck rules and test how different IDEs behave.
