UNLESS I'm misinterpreting what's happening, in https://github.com/enola-dev/enola/issues/1799, it seems to me that in my mono-repo project I've hit the limit of passing (all) `*.java` files as arguments to `google-java-format`. @cushon would you be open to a PR allowing e.g. to specify the list of files to format in a file passed with an `@` argument?
