!! Thanks for catching that. That actually means there's a small bug (or 
a missing feature) in Eshell: it doesn't support redirecting stdout and 
stderr to separate places when using synchronous subprocesses.

I've added a note about this to esh-proc.el (fixing it would probably be 
tricky), and changed 'message' in the tests to be 'princ'. See attached; 
I'll probably merge this tomorrow unless you catch any remaining issues.
