Why this change?

[jennyz, 2016/12/22 22:45:21]

I thought you suggested me to move it to ChromeExtensionsAPIClient, see your
previous comment:

"If you're convinced we can't implement this in //extensions, this should go on
the ChromeExtensionsAPIClient."

https://codereview.chromium.org/2379573008/diff/220001/chrome/browser/extensi...

Maybe I misunderstood?

[Devlin, 2016/12/27 17:08:00]

Yes.  But why do we need to put a newline here?  It seems against clang format,
is inconsistent with line 56 below, and isn't relevant to this change.

[jennyz, 2016/12/29 05:16:03]

Done.
