Added dig completion. For now +tries=### +retry=### +domain=### +bufsize=### +ndots=### +edns=### are missing as I'n not sure how to handle this properly. Generally, this completion feels more like a hack for me.

dig manpage

Usage:  dig [@global-server] [domain] [q-type] [q-class] {q-opt}
            {global-d-opt} host [@local-server] {local-d-opt}
            [ host [@local-server] {local-d-opt} [...]]
Where:  domain    is in the Domain Name System
        q-class  is one of (in,hs,ch,...) [default: in]
        q-type   is one of (a,any,mx,ns,soa,hinfo,axfr,txt,...) [default:a]
                 (Use ixfr=version for type ixfr)
        q-opt    is one of:
                 -x dot-notation     (shortcut for reverse lookups)
                 -i                  (use IP6.INT for IPv6 reverse lookups)
                 -f filename         (batch mode)
                 -b address[#port]   (bind to source address/port)
                 -p port             (specify port number)
                 -q name             (specify query name)
                 -t type             (specify query type)
                 -c class            (specify query class)
                 -k keyfile          (specify tsig key file)
                 -y [hmac:]name:key  (specify named base64 tsig key)
                 -4                  (use IPv4 query transport only)
                 -6                  (use IPv6 query transport only)
                 -m                  (enable memory usage debugging)
        d-opt    is of the form +keyword[=value], where keyword is:

                 +[no]tcp            (TCP mode, alternate syntax)

For now +tries=### +retry=### +domain=### +bufsize=### +ndots=### +edns=### are missing as I'n not sure how to handle this properly.

Something like

function __fish_complete_dig
    set -l token (commandline -ct)
    switch $token
        case "+tries=*" "+retry=*" # ...
            printf '%s\n' $token(seq 0 50)
complete -c dig -a '+tries=' -d 'Set number of UDP attempts'
complete -c dig -a '(__fish_complete_dig)'


This is assuming that 'dig +tries 50' is invalid.
