Please add a space between `-t` and `16,17`.

To be honest, I'm not a fan of this command. In those few cases it was
interesting to see, we often wanted to see all the information. And the
full dmidecode -t 17 output is just too much for the report.

Not to mention the quite complicated `grep | sed | sort` part that might
break on some systems that report things differently.
