<i>I'd</i> take the time to make the fix, update the indenting, fix up the inconsistencies, and all that. I know all about the Broken Windows Theory (<a href="http://en.wikipedia.org/wiki/Broken_windows_theory" rel="nofollow">http://en.wikipedia.org/wiki/Broken_windows_theory</a>), and have seen it in practice in too many places to ignore things like this and let them "slide".<p>You let one slide, then another, then another still. Eventually, you start getting little mistakes like this everywhere, because <i>all</i> of your code is ugly and difficult to read, and you have built up just mountains of technical debt.
