Proper indentation is a visual thing.

Sure, its easy to be consistent when you first type code -- I have my editor set to convert tabs to 4 spaces on input for pretty much every programming language I use. But its when you pick up a piece of someone else's code who used a different convention; or you cut and paste between files; or grab a snippet off the 'net; or just move a bit of code from one level to another...
The only reliable method is to squelch every line and re-indent. Life's too damn short for such pointless, affected, self-inflicted make-work.
