nit: indent at the beginning of the continuing line.

[stevenjb, 2013/08/21 17:38:49]

I don't think there is a nice way to format this, so I went with what
google-clang-format suggests and moved the -> to the next line and indented
that.

Should we add a DCHECK(!network_name.empty())?

[stevenjb, 2013/08/21 17:38:49]

No, we shouldn't crash in that case, it's not an error, it just means that a
network somehow has an empty name. (i.e. it's logically possible, but shouldn't
happen in practice). I replaced 'never' with just 'shouldn't'.
