Undesired 3-spaces indentation used in the sample code of the "Making Your Program Interactive" section of the "Getting Started with Java" tutorial

[brlin-tw]

In Making Your Program Interactive - Getting Started with Java - Dev.java, the following sample code is featured:

void main() {
   IO.println("Hello world!");
   var name = IO.readln("What is your name? ");
   IO.println("Hello " + name);
}

which uses 3 spaces instead of 4 as shown in the previous sample code, causing inconsistency and additional cleanup effort if one wanted to version control it for whatever reason:

void main() {
    IO.println("Hello, World!");
}

I would like to make a patch, however the current page content doesn't seem to match with the following file which seems to be the intended source:
