(info "(elisp)Output from Processes")

   It is impossible to separate the standard output and standard error
   streams of the subprocess, because Emacs normally spawns the
   subprocess inside a pseudo-TTY, and a pseudo-TTY has only one
   output channel. If you want to keep the output to those streams
   separate, you should redirect one of them to a file--for example,
   by using an appropriate shell command.
