Re: Word splitting with zsh fix

[Roumen Petrov <bugtrack@roumenpetrov.info>]

Hi Raúl,

I would like to know if option SH_WORD_SPLIT is set problem is solved too ?

Test case:
===============================
#!/bin/zsh

VAR="v1 v2"

for V in ${VAR}; do
  echo V1=$V
done

setopt SH_WORD_SPLIT
for V in ${VAR}; do
  echo V2=$V
done
===============================
When SH_WORD_SPLIT is set zsh work as bash, ksh, ash etc.
