Indent?

[liberato (no reviews please), 2015/12/07 19:04:39]

cl format will simply put it back.

It's strange it doesn't put back l.107. This may be a bug in git cl format
(either way).

[dcheng, 2015/12/09 01:41:50]

I don't think this is a bug. This is one of the points that the style guide
doesn't explicitly make a ruling on, so clang-format just picked one way to be
consistent.

You could make a good argument that this is how templates are formatted, e.g.:
template <typename T>
class scoped_ptr {
  // ...
};

 
   // Returns the supported codec profiles of video encode accelerator.
   virtual VideoEncodeAccelerator::SupportedProfiles
       GetVideoEncodeAcceleratorSupportedProfiles() = 0;
