Allow multiple non-option argunments, use last

Browse Source 
Allow more than one non-option arguments. Use the last one as the port
name, ignore others.

Rationale. Allow easily setting a default port using an alias or
script. The port can then be overriden by a subsequent argument. E.g.

  alias picocom='picocom -b 115200 /dev/ttyS0'

  picocom               <-- call with default port
  picocom /dev/ttyUSB0  <-- override default
