           Summary: Tshark custom columns: Why don't I get an error
                    message?

          Platform: x86

          Severity: Minor
          Priority: Low

Build Information:
$ tshark -v
TShark 1.6.0rc1 (SVN Rev 37186 from /trunk-1.6)

Running on Windows XP Service Pack 3, build 2600, with WinPcap version 4.1.2

Correct syntax:
$ tshark -r test.pcap -R "frame.number<6" -o column.format:""No.","%m",
"tcp.port", "%Cus:tcp.port", "udp.port", "%Cus:udp.port""
  1  55556,53
  2  53,55556
  3 1685,80
  4 80,1685
  5 1685,80

I get an error message, when I make a typo: %Cu:udp.port (instead of
%Cus:udp.port)
$ tshark -r test.pcap -R "frame.number<6" -o column.format:""No.","%m",
"tcp.port", "%Cus:tcp.port", "udp.port", "%Cu:udp.port""
tshark: Invalid -o flag "column.format:No.,%m, tcp.port, %Cus:tcp.port,
udp.port, %Cu:udp.port"

Why don't I get messages for the following typo's?
$ tshark -r test.pcap -R "frame.number<6" -o column.format:""No.","%m",
"tcp.port", "%Cus:tcp.port", "udp.port", "%Cust:udp.port""

  5 1685,80

$ tshark -r test.pcap -R "frame.number<6" -o column.format:""No.","%m",
"tcp.port", "%Cus:tcp.port", "udp.port", "%Custttttttttttttt:udp.port""
