This exception doesn't make it clear that the error is in .arclint, and loses the .arclint path.

You can wrap it in PhutilProxyException to get the best of both worlds, I think.

I agree, but it seems that we don't print the output from proxied exceptions. I'll update the diff and include the output.

Wrap exception in PhutilProxyException
