I was not thinking about that (sorry if I confused you)
_split_longopt aims to ease the use of $prev and AFAIK especially in the case
where --in=blah has to be used.
But I don't know enough about the use of this function to push any advise here.

but in the previous email I was thinking about replacing the following :
>     COMPREPLY=( $( compgen -W '--help --quiet --in --out --action \
>         --examples --showinfo --lowercase --uppercase \
>         --printprefix --printsuffix --maskprefix --masksuffix \
>         --printcompressed --printuncompressed \
>         --printfulluncompressed' -- "$cur" ) )
by :
[[ "$cur" == -* ]] && _longopt ipv6calc

BUT after a quick look at the ipv6calc --help 2>&1 output it
seems it's not well enough formatted to permit this kind of
automation. (some options are not documented in --help, or several
different are on the same line what's not currently handled by _longopt)
so ... forget all about what I said :)

Exception that :
1) some options are missing anyway (I repeat I don't know the program nor I use ipv6 ;)  :
--machine_readable, --show_types, --db-geoip, --printstart, --printend, --db-ip2location-ipv4
--db-ip2location-ipv6, --db-geoip-default
(http://cvs.deepspace6.net/view/ipv6calc/lib/ipv6calchelp.c?rev=1.17&content-type=text/vnd.viewcvs-markup)
[ here (programs with compile-time features/help-output) is the power of _longopt ]

2) IMHO the long-options COMPREPLY should happen if [[ "$cur" == -* ]]
3) so no completion happens otherwise (return 0) (as it seems like input files aren't accepted arguments)

I wish I'm not too nitpicking.
