commit 613e384e5072edf8d455710be40a4d94d4b27809
Author: G. Branden Robinson <g.branden.robin...@gmail.com>

[troff]: Implement recursive node dumping (8e/9).
Derive class `break_char_node` from struct `container_node`.
* src/roff/troff/node.h (class break_char_node): Do it. Drop
pointer-to-node member variable and declaration of destructor.
* src/roff/troff/node.cpp (break_char_node::break_char_node): Migrate
constructors to use new base class.
(break_char_node::~break_char_node): Drop; our base class handles
destruction of contained node(s).
Changes `pline` request output as follows.
-{"type": "break_char_node", "diversion level": 0, "is_special_node":
false, "break code before": 2, "break code after": 0, "terminal_color":
"default"},
+{"type": "break_char_node", "diversion level": 0, "is_special_node":
false, "break code before": 2, "break code after": 0, "terminal_color":
"default", "contents": [{"type": "glyph_node", "diversion level": 0,
"is_special_node": false, "character": "-"}]},
