hello Bart,

i added this code in uze.zsh and spotted a bug thanks to my test
suite (https://github.com/zsh-uze/uze/blob/master/t/100_dump.t)
the thing is the first line doesn't survive to the (@f) modifier
so:

    print -l '' a '' b | read -r -d '' lines
    for it ( "${(@f)lines}" ) l "* ($it)"

got:

    * (a)
    * ()
    * (b)

expected:

    * ()
    * (a)
    * ()
    * (b)

so i reverted the code for the moment waiting for
the moment i can use a code closer than yours.

regards
marc
