Wireshark · Wireshark-dev: Re: [Wireshark-dev] Swap 'v'|'V' options for editcap and mergecap

[chuck c <bubbasnmp@xxxxxxxxx>]

#15483 - Longest journey, first steps...  https://gitlab.com/wireshark/wireshark/-/merge_requests/4611

I was hoping to work towards (for -h and -v) something like LONGOPT_CAPTURE_COMMON in https://gitlab.com/wireshark/wireshark/-/blob/master/capture_opts.h

and ws_log_print_usage() in https://gitlab.com/wireshark/wireshark/-/blob/master/wsutil/wslog.c.
