commit 71be7fc1482d498a1efce1ff5d1068aa21499508
Author: G. Branden Robinson <[email protected]>
AuthorDate: Mon Sep 1 03:49:28 2025 -0500
[troff]: "Asciify" vert motion nodes as nothing.
...suppressing non-actionable diagnostic message. (Vertical motion
nodes are produced by the `\v` escape sequences and other formatter
facilities.)
* src/roff/troff/node.h (class vmotion_node): Declare `asciify` member
function, thus overriding base class.
* src/roff/troff/node.cpp (vmotion_node::asciify): New member function
does "nothing" in the same way that those of `line_start_node` and
`vertical_size_node`s do: delete the `this` object and return.
