   If a filter function is specified, it is expected to take a single
   string argument, and it will be called with each line of the
   subprocess's output. Each line has had the trailing newline character
   trimmed.
 
   If the command fails, as indicated by a nonzero exit status, gclient will
   exit with an exit status of fail_status.  If fail_status is None (the
   default), gclient will raise an Error exception.
