commit 63c05ebea922165cfe3cc355c9744ed4f8b1beb0
Author: G. Branden Robinson <[email protected]>
AuthorDate: Tue Oct 21 11:14:06 2025 -0500
[troff]: Slightly refactor; boolify.
* src/roff/troff/input.cpp (process_input_stack): Rename `suppress_next`
local variable to `ignore_next_token`, and demote it from `int` to
`bool`. Assign to it with Boolean rather than integer literals.
