Well, maybe I wasn't that clear, sorry.

The above "solution" was to handle the "alternative system". We can always wrap
everything inside _have()s. Quick example:

_have tightvnc && { [..code..] } && complete -f tightvnc tightvnc
_have vnc4viewer && { [..code..] } && complete -f [..]

_have vncviewer && {
    // we know it's an alternative, handle it
    [..code to get $alternative...]
    case "$alternative" in
    [..see above..]
    esac
}

I haven't tried it, but wouldn't this work? Without adding any hassle to
maintainers.

Kindly,
David
