[eqn]: Drop ersatz copyright symbol '(C)'.
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.
