commit 524234f94e57c87d90a0936ec72aacd30988cc67
Author: G. Branden Robinson <[email protected]>
AuthorDate: Wed Aug 28 15:00:24 2024 -0500
[troff]: Trivially refactor (`causes_tprint()`).
[troff]: Boolify and rename member function of `node` class hierarchy to
`causes_tprint()`. This function indicates whether the node requires
certain formatter state (roughly, changes to the environment) to be
flushed to output before the next node is written ("tprint"ed).

Some gripes:
1. I wish I knew why no one ever wrote a design document for this
formatter.
2. Why make `causes_tprint()` (formerly `force_tprint()`) a pure
virtual function when practically everything that overrides it has
it return `false` (formerly `0`)? Why not make it impure and return
false in the base class? (...said somebody who's likely to cut his
thumb on one of C++'s sharper edges any minute now.)
3. Why all the separate member function definitions for
single statements? Isn't the idiomatic C++ thing to define this
inline as part of the class declaration?
