But if you were messing around with the tab size you obviously wouldn't
indent like that; you'd make every indent level a tab and just set the tab
width to your desired indent size.

Not if you set the tab size smaller.  That was my original point:  if you
indent with tabs, you can have the indents as wide or as narrow as you wish.

But that code was clearly formatted with the inherent assumption that tabs
are exactly equivalent to eight spaces; someone using a nonstandard tab size
simply wouldn't have written it that way.

Mixing tabs and spaces in this way will indeed cause parts of the code to be
misaligned where that assumption is false, but that's not an issue if you
consistently indent with tabs only.  (For that matter, IMHO, if you want
something that's guaranteed to be exactly eight spaces wide, it's safest to
simply use eight spaces.  Admittedly, that will increase the file size a
