Done here. For the ones below that are pretty much one-liners, I find the
comments noisy rather than helpful.

[huangs, 2017/01/31 17:40:04]

Would it be clearer to render |kUninstallArguments| from params?  I.e.:

  std::wstring uninstall_args = std::wstring(L"--uninstall") +
      (system_level ? L" --system-level" : L"") +
      (multi_install ? L" --multi-install --chrome" : L"");

...
  
  uninstall_args.c_str();

Done.

please add comment on why.

I'm not sure there is any interaction. chrome_app_guid()'s behavior is solely
