`trimTrailingZeros` with `short` removes opening bracket for wrapped arrays

[Gavin Kistner]

a = [1,2]
neatJSON(a,{ wrap:true, indent:"", decimals:3, trimTrailingZeros:true })
// [
// 1,
// 2
// ]

neatJSON(a,{ wrap:true, short:true, decimals:3, trimTrailingZeros:true });
// 1,
// 2]

Expected output:

[1,
 2]
