[troff]: Implement recursive node dumping (5a/9).
* src/roff/troff/node.h (class space_node): Specialize (override)
`dump_properties()` for this class.
* src/roff/troff/node.cpp (space_node::dump_properties): New member
function reports value of `hunits` property.
Changes `pline` request output as follows.

false, "hunits": 2500}]
