mmroff.1 came from mmroff.7.
Following changes will be delivered later: groff_www.7, groff_char.7,
groff_ms.7 and roff.7.
File removed can also be found at following location:
ftp://daemon.jp.freebsd.org/pub/FreeBSD-jp/man-jp/work/contrib/
o remove a garbage line (dnsquery.1)
o add missing .El (expr.1)
o Q1 should be Ql (groff_mdoc.7)
o \fB.H\fP at the beginning of line should be prepended by \& (groff_mm.7)
in order to force .Rv and .Ex to output English text.
This is required for the .Rv and .Ex examples in groff_mdoc.7, since it
explains original groff_mdoc.7 bahavior (English text output).
Without this workaround, .Rv and .Ex output Japanese text, since
-dlang=ja_JP.eucJP selected Japanese versions of str-Rv-* and str-Ex-*.
