I had to stare at this for a few seconds to see that it's just a style change.
Can we avoid it in this patch?

Sure, this was done by 'git cl format'.
It's a little bit inconvenient not being able to run 'git cl format', or to have
to track down all the diff sections and revert some after it runs. :/

You should be able to run git cl format as it won't fix style of code that you
didn't change. Are you running it with -f for full file?
