Nit: make this a blank line, without the //

[tyoshino (SeeGerritForStatus), 2013/06/10 06:14:00]

Done. So, like net_error_list.h, L7 should be also blank line? Or we just should
split copyright notice and file comment?

[wtc, 2013/06/10 17:12:47]

The latter. I mainly want us to split the copyright notice and file
comment. As for L7, I would also use // as you do, but a blank line
would also be fine.

[tyoshino (SeeGerritForStatus), 2013/06/11 03:21:15]

All right. Thanks.
