Date: Tue, 20 Aug 2013 13:16:25 -0700

The basic problem is that (("a" 1 2)) is the same thing as (("a" . (1
2))). Is that a list of one three-item list, or is it an alist with
one entry, whose key is "a" and whose value is a two-item list? It
might be reasonable for `json-encode-list' to provide programmatic
control over this, but the current behavior isn't a bug.
