commit 84a10f2eeb643e6ee4406085ca248b659f959b3d
Author: G. Branden Robinson <[email protected]>
AuthorDate: Thu Sep 11 11:17:23 2025 -0500
[troff]: "Asciify" token nodes as nothing.
Token nodes are used only internally to manipulate the input stream;
they don't directly correspond to any sort of document feature.
* src/roff/troff/node.h (class token_node): Declare `asciify` member
function, thus overriding base class.
* src/roff/troff/node.cpp (token_node::asciify): Plant land mine with
`assert()`. Delete the `this` object and return.
