If you're indenting four spaces per level, then indent four spaces per
level. The code you posted would work perfectly if the indentation is
four spaces, then eight spaces, then twelve spaces. The problem is
that you have a stupid editor that's enforcing tabs instead of certain
multiples of spaces - get one that'll keep them all as spaces and you
won't have a problem.

Or use actual tabs, and set the displayed tab width to whatever you
feel like. That works, too. Neither option causes any problems with
any sane tools.
