the presubmit is not fond of your examples... perhaps shorten?

[dzhioev (left Google), 2015/06/16 00:18:16]

Unfortunately this is not an example, but a part of generated file, so I can't
shorten it. 

[Dan Beam, 2015/06/16 00:19:40]

ah, either do some string splitting magic or NOPRESUBMIT=true then?
