fix indent (drop stream_id to next line?)

I can fix this but I thought this was in line with the styleguide?  Do you mind
setting me straight?
(I thought I was doing something similar to "AndAnotherLongFunctionCall" in
http://www.chromium.org/developers/coding-style)

Hmm!!

I've always done either ThisIsARatherLongFunctionCall or
ThisIsAnotherLongFunctionCall but never AndAnotherLongFunctionCall as that seems
like a mixing of indentation styles

http://google-styleguide.googlecode.com/svn/trunk/cppguide.xml?showone=Functi...
doesn't explicitly forbid the mixing of indentation styles but does seem to
either wrap at the ( or drop to next line + 4-space indent

+      media::kAudioStreamError));
