This is fairly far down in the weeds as feature changes go, but since it technically is one, I'm submitting it to the list for comment.
It involves troff's page description language (a.k.a.
"device-independent output format"), so if you don't care about parsing
that, you can skip over this.
o GNU troff output now reports unbreakable spaces (those produced with
the `\~` escape sequence) as word breaks with the documentary 'w'
command, just as regular breakable spaces do.
You could be forgiven for not remembering what the 'w' output command
is. Technically, the answer is "nothing". Here's what groff_out(5)
says in Git HEAD.
w Indicate an inter-word space. No action is performed; the
command is present to make the output more easily parsed. Only
adjustable, breakable inter-word spaces are thus described;
those resulting from \~ or horizontal motion escape sequences
are not. GNU troff issues this command but groff's output
driver library ignores it. See h and H.
(And, hah, I see I need to add a documentation change to my patch.)
Right now this code lives only in a branch in my working copy. In case
it need be said, I have _zero_ intention of putting it into groff
1.23.0.
Please follow up to <https://savannah.gnu.org/bugs/?64356> with
comments.
