Comment 4 for bug 1699445

I have a fix (attached) for 3.15 and a different one (not included) for the ai and longin (i.e. scalar) cases in 3.16, but in 3.16 the aSub input links can initialize arrays, and there is a new routine dbLoadLinkArray() for doing that. This calls the JSON parser for the conversions, hence no hex as I discussed previously unless we switch to the JSON5 syntax. I do want to do that, but it isn't a simple change and will depend on my yajl-2.1 branch.
