troff(1): Cosmetically revise copyright notice.
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.[1] 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.
