allowEmptyArrays option disrespects arrayFormat #525
Description
allowEmptyArrays option was intruduced in version 6.12.0
Without this option
qs.stringify({ foo: [], bar: baz })
// 'bar=baz'
With this option
qs.stringify({ foo: [], bar: baz }, { allowEmptyArrays: true })
// 'foo[]&bar=baz'
However, I believe that with arrayFormat: 'comma' option, it should result like this:
qs.stringify({ foo: [], bar: baz }, { allowEmptyArrays: true, arrayFormat: 'comma' })
// 'foo=&bar=baz'

I understand that expectation, but when
commaRoundTripis anything buttrue,commadoes a bunch of weird stuff, and whencommaRoundTripistrue, i think'foo[]&bar=baz'would be the expected output?
