Custom statusMessage

[NikunGe]

Hi,

I am proxying to a server that is setting a custom statusMessage in the response (> 400). The statusMessage is not being sent back through the proxy, as requestjs pipeDest function is not automatically setting it. Please see here: request/request#2694

Since it is not being set by requestejs automatically, can we set it before calling pipe?

Thank you!
