I hope you are not talking about adding demandoc to the base! Incidentally FreeBSD man fails at properly formatting deroff.1 man page. It produces -mm Remove titles, attachments, etc., as well as ordinary = troff constructs, from or mm documents. nroff -man produces this: -mm Remove titles, attachments, etc., as well as ordinary = troff con=E2=80=90 structs, from ms(7) or mm(7) documents. 9 man -mm Remove titles, attachments, etc., as well as ordinary troff constructs, from ms(7) or mm documents.=20 =09 mandoc man page says: By default, the input language is automatically detected for each file: if = the first macro is Dd or Dt, the mdoc(7) parser is used; = otherwise, the man(7) parser is used. With other arguments, -m is = silently ignored. So either it is using the wrong parser or the parser is doing the wrong = thing!=
