I checked in a change so that the "-q" flag, when you're reading a
capture file with "-r", suppresses packet output; this can be useful if
you're using a "-z" flag and only want Tethereal to print the statistics
when it's done, rather than also printing packet information.

It should probably also suppress packet output if you're capturing
without "-w", and either give a warning or suppress packet output if
you're capturing with "-w" and "-S" (as using "-q", "-S", and "-w" would
just be equivalent to "-w", with "-S" turning packet output on and "-q"
turning it back off again).
