Empty Bash array wrongly highlighted as error in "do" construct

[Victor Engmark]

To reproduce, simply cut'n'paste this into a new file:

#!/usr/bin/env bash
foo=()
while true
do
    bar=()
done

The two sets of parentheses will be formatted differently in VIM 7.3: With a black terminal background as the default, the first construct shows up as a dark blue "(" followed by a dark blue ")", both on a black background. The second is a white "(" on a black background followed by a white ")" on a red background, the latter indicating an error. These two instances should be formatted the same.
