I found a small error in my program (in red the fix), but there is no need to modify it to process many files:
Code:
$ cat script.pl 
use warnings;
use strict;

die qq[No argument\n] if @ARGV == 0;

my @prev_line;

while ( <> ) {
        chomp;

        if ( /\A\*\*/ .. eof ) {
                next if m/\A\s*\Z/;
                if ( m/¦/ ) {
                        if ( @prev_line ) {
                                printf qq[%s\n], pop @prev_line;
                        }
                        push @prev_line, $_;
                        next;
                }

                printf qq[%s\n], (pop @prev_line || qq[]) . $_;
                next;
        }

        printf qq[%s\n], $_;
}

And run it like:
Code:
$ perl -i.bak script.pl /tmp/grep/*
