Automaticall open new diagram

[Jeffrey Kern <the xtype gmail com>]

"-Automaticall open new diagram if now chosen at start."

Can we add a command line flag to disable this?
  -w, --withholdnew                    Don not open new diagram.

Or possibly something in the ~/.dia/diarc would suffice.

I do not think that it should be forced as the default behavior.

Thanks,
