Wow, just the process of sneaking in this exploit has layers. Here, it's the presentation of diffs with "+" and "-" line prefixes creating noise that's easy to miss. I bet we'll start seeing tools add a divider between the prefix column and the contents to make changes like this easier to spot.
That said, does GCC accept every non-printing character as whitespace? If not, they could probably have achieved the same thing with a narrow-nonbreaking-space character or similar.
