Well I mainly did this because that is what parser does everywhere it takes
multiple values, it never seems to use realloc for anything like this.

I'd prefer the parser code to be consistent rather than useful, since nobody
likes to touch or maintain it, and coming back in a few years wondering
why this is realloc based and the rest isn't could be confusing.
