Subject: [PATCH 2/2] python-linux-procfs: pflags: Ignore non-existent pids or
 process names

If the user enters a non-existent pid or process name, skip over it.

Also, if the user enters nothing but a non-existent pid, then don't
calculte max_comm_len since you can't take the max of an empty list.
