[PD] pd --help doesn't work

[Piotr Majdak]

Hi!

I'm used to execute "pd --help" to get list of pd switches. After an update to 0.38.3 this command doesn't work: nothing happens, pd doens't even start. The same behaviour for starting pd with an unsupported switch or a misspelled supported switch.

I noticed that "pd --listdev" shows the device list in pd's native message list. How can I get "pd --help" to help? 

br, Peter
