src/roff/troff/env.cpp: Revise copyright notice.
Add copyright notice for myself. I have never executed copyright
assignment paperwork with the FSF, so my "legally significant"[1]
changes to this file[2] can't be under the FSF's copyright.
(I retain an FSF copyright notice corresponding to all changes not
authored by me--and which are above the "legal significance"
threshold--because I don't know who _has_ filed copyright assignment
paperwork with the FSF; I know only that I [and Ingo Schwarze] haven't.)

commit c9cbe4ba3cd3d44b7e1535fd5de987013fd302a6

[troff]: Fix Savannah #67219.
* src/roff/troff/env.cpp (distribute_space): Fix expression involving
C++ `static_cast<>` operator to stop permitting integer division
within, leading to undesired loss of precision when reporting the
amount of "spread" applied when performing adjustment, as configured
by the `spreadwarn` request.
Fixes <https://savannah.gnu.org/bugs/?67219>. [Problem introduced by
me in commit 8b6ccbce48, 13 May. --GBR]

[1] "A change of just a few lines (less than 15 or so) is not legally
significant for copyright." Conversely, >= 15 lines would be.

[2] The history of this file supplies an interesting test case for the
"legal significance" threshold if we disregard cumulativity and
apply it only to individual commits. (It's not clear to me which
interpretation the GNU Maintainers' Guide intends the reader to
infer.) The first commit I made that netted at least 15 lines of
additional code was this.
commit 39ffa368dc6a1de4c11cf3f4f5b8594d3c974173
Author: G. Branden Robinson <[email protected]>

[troff]: Validate a font family before using it.
(...which funnily enough got reverted and reimplemented. See
https://savannah.gnu.org/bugs/?64155 for history.)
Assuming that commit were still present, the earliest copyright date
for myself that I could apply to this file was 2023. However, I made
many changes before that time. How much did I change the file
beforehand?

Does some quantum of originality under principles of copyright
lurk within ~250 lines of change even if no individual change reaches
the 15-line threshold of "legal significance"? Applying a cumulative
interpretation shifts the first date associable with my name to 2020,
with two commits, one in that year and one in 2018 netting 16 lines
of additional code.
