 Also see PRs gnu/4930, gnu/8321, bin/9502, and the *roff documentation
 (which documents that yr is the last 2 digits of the year), and groff
 v1.15 (which keeps it years since 1900 and adds Y2K fixes to the mandoc
 and me macros based upon this.  ms didn't need fixing and orig_me
 (from /usr/src/share/me) is not part of groff but also expects yr to be
 years-since-1900).
 
 \(yr holding "the last 2 digits of the year" is broken as designed,
 since then there is no way for *roff macros to know the century.
 The fix for bin/9502 made FreeBSD incompatible with everything else;
 I think it should be reverted.
