--- walk_meta walks a Pandoc Meta object, applying the filter to each node
--- and recursing on lists and objects. It mutates the meta object in place
--- and returns it.
---
--- It performs slightly more work than a regular walk filter because of the
--- ambiguity around single-element lists and objects.
