Are you aware that this tiny change (-man -> -mandoc) will break some of our
core FreeBSD tools, and a lot of third-party tools which we use in the base
system? Not to mention some FreeBSD ports which may fail as well.

This will affect all FreeBSD releases/branches (12/13/14/15) that we support. A
possible workaround is to downgrade the groff port to 1.22.4 locally.

Checking our repos I see that we need to change ~100 files:

for i in freebsd-{src,ports,doc};do (cd $i && printf "$i "; git grep 'roff.*
-man[^d]' |wc -l );done
freebsd-src 35
freebsd-ports 51
freebsd-doc 9

Thinking about the issue - maybe we should just patch the FreeBSD port of groff
and revert this change. It hurts a lot of our users.
