o Update README files etc. from nvi-1.79 so they have the correct info

o make port.h empty since we there is nothing we lack
o include <sys/param.h>, not <sys/types.h> in files that use MIN/MAX macros
o add perl api support since we have libperl (off by default)

+=head1 NAME
+
+nviperl - nvi with embedded perl
+
+=head1 SYNOPSIS
+
+    :perl require 'wc.pl'
+    :perl wc
+    :,$perldo $_=reverse($_)
+
+=head1 DESCRIPTION
+
+nvi with embedded perl allows you to run perl commands from within nvi.
+Two additional commands are made available when you enable the perl
+interpreter:
+
+=over 8
+
+=item * perl cmd
+
+The perl command passes the specified commands to the perl interpreter.
+The C<$VI::ScreenId>, C<$VI::StartLine> and C<$VI::StopLine> are set.
+To find out how to maniplulate the nvi screens, see L<VI>.
+
+=item * perldo cmd
+
+The perldo command runs the specified commands on each line of the range
+(every line of the file if no range specified).  Before running the
+command the line is copied into $_.  If the command returns a true value
+the line is replaced by the new value of $_.
+
+The perldo commando does B<not> set the C<VI> variables.  (If you think
+this is a bad idea, tell me.)
