badly formatted man pages under solaris 
WORK IN PROGRESS
man pages of non solaris software is sometimes badly formatted, because the solaris nroff use limited macros (cannot understand mandoc).
Install and use 
groff instead of the original 
nroff
groff -mandoc -T ascii -t -P -c /usr/pkg/man/man1/pkg_info.1
You can put this into a script
#! /bin/sh
exec groff -Tlatin1 -mandoc -P -c "$@" | exec less
The others do not work
nroff -mandoc -Tlp /usr/pkg/man/man1/groff.1
man -M/usr/pkg/man -r -T-mandoc pkg_info
 
-  textproc/mdocml
-  configure etc/man.conf
