> Synopsis: groff 1.11 Y2K bug
The originator of this PR wanted to say is there are still
inconsistencies about the handling of the number register `yr'
even after bin/9502 closed.
We modified troff/input.cc so that the `yr' value can be
the "last 2 digits of this year" after 2000. But some macros
assume that the `yr' has the value of the "year minus 1900."
/usr/share/tmac/mdoc/doc-common:.nr Yr \n(yr+1900
/usr/share/tmac/tmac.e:.nr y2 \n(yr%100
/usr/share/tmac/tmac.e:.nr y4 \n(yr+1900
/usr/share/tmac/tmac.orig_me:.ds td \*(mo \n(dy, \n(yr+1900
/usr/share/tmac/tmac.s:.nr *year \n[yr]+1900
GNU groff team changed their documentation since groff-1.12,
but doesn't touch their implementation of the `yr' register.
\en(y2 R year (last two digits only)
\en(y4 R year (all digits)
\en(yr R\(sc year minus 1900
