serialization and wrapping

Hi,

I'm working on the serializer (bug 422403), and I would like to know if, 
when we want to wrap at 72 characters for example, line break (\n, \r or 
\r\n) should be or not included in this 72 characters. In other words, 
"\n" is the character number 72 or number 73 in the line ?

In the actual trunk, it seems that it is included in these 72 
characters, but I want to be sure that it is correct.
