/proc/pid/comm is at most 15 characters (plus NUL), so specifying a longer `--command` value will never match. Truncate it to the maximum and warn about it. Note that the manpage speaks about `TASK_COMM_LEN`, but that isn't defined anywhere. So define it ourselves. Fixes #33 [1] https://man7.org/linux/man-pages/man5/proc_pid_comm.5.html
