Force show lsof port numbers to get emhttp port

[eschultz]

Without the -P argument lsof will output port names (e.g. 'http') instead of '80' and the regex used in the grep fails to parse anything useful.

Aie, aie oversight by me. I use a non-standard port myself and didn't notice the disappearance of the -P option.

Thanks for the corrections.
