Hmm, I wonder what the point of doing "tshark -w - > /some/file" is when
you could just do "tshark -w /some/file"?

Anyway, I tried it and it seems to work better, although compared to the
0.99.6 version, the output differs given the same options.  I would
expect the output to be the same, no?

Running "tshark.exe -p -i 4 -f icmp -c 4 -w - > tsharktest.cap":

tshark-SVN-23133:
"C:\wireshark-gtk2\tshark.exe" -r tsharktest.cap
  1   0.000000 192.168.1.100 -> 192.168.1.1 74
  2   0.000272 192.168.1.1 -> 192.168.1.100 74
  3   1.002940 192.168.1.100 -> 192.168.1.1 74
  4   1.003186 192.168.1.1 -> 192.168.1.100 74

tshark-0.99.6:
"C:\Program Files\Wireshark\tshark.exe" -r tsharktest.cap
No log handling enabled - turning on stderr logging
  1   0.000000 192.168.1.100 -> 192.168.1.1 74 ICMP Echo (ping) request

be working.  I could be doing something wrong since I hardly ever use
tshark, but I compared the output of a 0.99.6-tshark with the output of
an SVN-23125-tshark with the following command line:

When using "-w -" you're telling tshark to write the *PCAP* data to 
stdout so normally I'd do:

tshark -w - > /some/file

And then:

tshark -r /some/file

to read it back in/display it.
