vertical lines in the file

Stream: new members

[Michael Beeson]

Those nice vertical lines are a big help for alignment. My first three files had them spaced two characters apart. My fourth file,
created by "new file", has them spaced four characters apart. How can I get them to be two characters apart like the other files?
(Probably I created those files by "save a copy", so I guess I could do that again, but anyway I'd like to know how to control this.) I'm using VS Code.
