    [tmac]: 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.
