How about this one:

    .some-css-rule { padding-left:50px; padding-right:50px; margin-left:50px; margin-right:50px; }

I run into examples like this a lot and have yet to find an elegant way to deal with it. Honestly, I'd like to see if there's a simple solution.

I find that I spend a lot of time in my editor crafting regular expressions to do clever replacements and I've yet to get so good at it that it doesn't distract me from my editing.
