src/.../grotty/grotty.am: Revise copyright notice.
Add a copyright notice for myself. I've never executed copyright
assignment paperwork with the FSF, so my (cumulatively) "legally
significant"[1] changes to this file from 2021 to 2024[2] can't be
under the FSF's copyright.
Drop ersatz '(C)' copyright symbol. Software developers have long
labored under the no-longer-correct misconception that omitting a
copyright symbol from one's notice was a fatal defect that effectively
placed the work in the public domain. That stopped being true as of 1
March 1989.[3] Further, prior to guidance issued by the U.S. Copyright
Office in the decades since, the use of "(C)" as a substitute for a
copyright sign _may not have sufficed_ to prevent the copyright notice
from being regarded as defective. The Copyright Office, then and now,
prefers the abbreviation "copr." when © is typographically
unavailable.[ibid.] Nowadays, its advice is that "c" (note lowercase)
is an "acceptable variant", that _may_ retain the efficacy of the
copyright notice. The word "copyright", spelled out in full, also
suffices per that resource, and is already present in this notice.
[1] "A change of just a few lines (less than 15 or so) is not legally
significant for copyright." Conversely, >= 15 lines would be.
