Indent. Please just run `git cl format` over your CL before you upload it; it's
going to save you a bunch of unnecessary review roundtrips for style errors.

[Alexander Agulenko, 2015/11/04 09:42:29]

I have already run this command but git ignored whitespace-only changes.

Done.

[Bernhard Bauer, 2015/11/04 09:59:59]

Ok, then you probably should configure Git not to do that 😃
