I don't know a lot about that excepted that COPYING doesn't contains
anything about CeCILL (which AFAIR is GPL-compatible isn't ?)

only list short options which have not a long equivalient (I didn't
verified as I didn't find the man page on the web)

you can start from 1

[[ ${COMP_WORDS[i]} = -nwni ]] is also correct

I went over this issue some times ago
(http://www.mail-archive.com/bash-completion-devel@lists.alioth.debian.org/msg01042.html

I would have used ${COMP_WORDS[0]} = scilab-cli but it may also be
robust afterall. A simple condition like :
[[ ${COMP_WORDS[0]} = scilab-cli ]] && options=${options/-nw}
seems enough.

don't know (nor checked out) why, but if you're sure about that

should be COMPREPLY=( $( compgen -W "$options" -- "$cur" ) )
