Bug#361813: vim-common: mis-highlights valid sh code

[Justin Pryzby]

Package: vim-common
Version: 1:6.4-007+1
Severity: normal

vim displays the following with the ending brace of the function in
red, as if it were invalid:

dne ()
{
        [ -e "$1" ] && { echo "File exists: $1"; exit 1; }

        return 0;
}

But it is tested to work in {po,da,ba}sh.
