This script concatenates multi-line messages, printing them as it goes.

use strict;
use warnings;

my $buffer = q();

while(<DATA>)
{
    chomp;
    if(/KB[0-9]/)
    {
        $buffer .= $_;
    }
    else
    {
        print "$buffer\n" if $buffer;
        $buffer = $_;
    }
}
print "$buffer\n";

I hope it is of use.

Update:

I looked at this again and wondered how it was printing the last log message when I had forgotten to do a final print statement after the while loop. It was working because there was a blank line at the end of the __DATA__ file (I nearly said Data Division thus revealing a murky COBOL past).

Code now corrected.
