(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.
