If a command run by subprocess.check_call() exits because of a signal, e.g. SIGPIPE, Popen._handle_exitstatus() encodes the signal number as a negative return code. check_call() then raises that as a CalledProcessError, which describes it as "returned non-zero exit status -13". This is misleading and undocumented. 

CalledProcessError.__str__() should check if self.returncode is negative and if so return a string indicating that it was "signal 13", not "exit status -13". Better yet, it should include the descriptive name of the signal, e.g., SIGPIPE.

And, the documentation for the subprocess module should note that a signal is converted into a negative returncode.
