I am using Mail::Audit to process email. In order to process the message body, I need to create a text string out of the array reference handed to me by 
my $body = $item->body;

and I do 
$tbody  = join('',@$body);

The strange thing occurs with the following: Raw input containing 
<a style=3D"color: blue" href=3D"http://online.wsj.com/article/SB11966
+351958=
6211071.html?mod=3Dgooglenews_wsj">

is actually changed to 
<a style=3D"color: blue" href=3D"http://online.wsj.com/article/SB11966
+35195=
86211071.html?mod=3Dgooglenews_wsj">

What is not visible above is that in both cases the equal sign is followed by NL (x0A). It seems to shift the =NL combination one position to the left in the resulting text string. It happens only in the cases where the line contains "href".
