Now, this does quote inserted string which is good. Unfortunately, it is
still confused by inserted quotes ... 

_urpmi_media() {
    local source media brace
    local -a all_sources suf
    local context state line
    typeset -A val_args
    while read source media brace; do
        [[ "$brace" != "{" ]] && continue
        all_sources=($all_sources[@] $source)
    done < /etc/urpmi/urpmi.cfg

    _values -s , 'urpmi media' $all_sources
}

bor@cooker% urpmi --media Contrib\ CD,
Completing urpmi media
Contrib CD        Installation CD

So far so good. But if I now hit ENTER and try complete again ...

bor@cooker% urpmi --media Contrib\ CD,
No matches for: `urpmi media'

Looks like _values get confused by quoting on command line?
