Unbreak rwhod(8):

Browse Source 
- It did not work with GENERIC kernel after r250603 because
  options PROCDESC was required for pdfork(2).  It now just uses fork(2)
  instead when this syscall is not available.

- Fix verify().  This function was broken in r250602 because the outermost
  "()" was removed from the condition !(isalnum() || ispunct()).
  It prevented hostnames including "-", for example.
