[pfbtops]: Cosmetically revise copyright notices.
* src/utils/pfbtops/pfbtops.1.man:
* src/utils/pfbtops/pfbtops.c:
* src/utils/pfbtops/tests/smoke-test.sh: 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 these notices.
